Answer the question at the end by quoting:

Brotherhood of Man are a British pop group who achieved success in the 1970s. They won the 1976 Eurovision Song Contest with "Save Your Kisses for Me". Created in 1969 by songwriter and record producer Tony Hiller, Brotherhood of Man was initially an umbrella title for a frequently-changing line-up of session singers. Early on, they scored a worldwide hit with the song "United We Stand".
Keen to keep the established name alive, Hiller set about putting a new line up together. In 1972 he got together a trio of session singers, Martin Lee, Nicky Stevens and Lee Sheriden.  Sheriden was already known to Hiller as a songwriter and had a solo career. Lee had a solo single to his name and was a budding songwriter. Stevens had been classically trained, but had since adapted her vocals and was performing as a cabaret singer. The trio began recording together, but their first single, "Rock Me Baby", to be released at the end of 1972, was cancelled due to the release of the song by David Cassidy. Finally their first two singles "Happy Ever After" and "Our World of Love" were released in 1973. Neither single charted and soon after, another female vocalist was added to the line up, Sandra Stevens. Stevens (no relation to Nicky) had been performing as a big-band singer since a teenager in the late 1960s. She had sung with the Joe Loss big band and alongside Eve Graham (of The New Seekers) in club group, The Nocturnes.  Now signed to the Pye spin off label, Dawn, the quartet released their first single, "When Love Catches Up on You" in January 1974. It failed to chart, but the follow-up single, "Lady" became a hit in Europe. Encouraged by this, the group set about recording their debut album. The album Good Things Happening was released later in the year along with two more singles, but none of these found success. Before the record label folded, Brotherhood of Man released one more single in the Summer of 1975. This was the upbeat "Kiss Me Kiss Your Baby" and although failed to make an impression in the UK, became a big hit in Europe, reaching Number one in Belgium and Number two in the Netherlands as well as top 10 placings in other countries. Brotherhood of Man toured extensively in Europe, honing their stage act and harmonies, while Hiller, Sheriden and Lee worked on composing songs for their second album. Among them was a song Sheriden had largely written called "Save Your Kisses for Me".

Why was Rock Me Baby cancelled?

due to the release of the song by David Cassidy.

Some context: The Roots is an American hip hop band, formed in 1987 by Tariq "Black Thought" Trotter and Ahmir "Questlove" Thompson in Philadelphia, Pennsylvania, United States. The Roots are known for a jazzy and eclectic approach to hip-hop featuring live musical instruments. Malik B., Leonard "Hub" Hubbard, and Josh Abrams were added to the band (formerly named "The Square Roots"). Since its first independent album-length release the band has released 10 studio albums, two EPs, two collaboration albums (with other artists), and also collaborated on recordings and in live shows with a wide variety of artists in many musical genres.
The Roots originated in Philadelphia with Ahmir "Questlove" Thompson and Tariq "Black Thought" Trotter while they were both attending the Philadelphia High School for the Creative and Performing Arts. They would busk out on the street corners with Questlove playing bucket drums and Tariq rapping over his rhythms. Their first organized gig was a talent show in 1989 at the school where they used the name Radio Activity, which began a series of name changes that progressed through Black to the Future and then The Square Roots. In 1992, they dropped the "Square" because a local folk group had claim to the name.  Organix was the band's first album, released and sold independently in 1993. It drew offers from music labels, and the band signed with DGC/Geffen. The Roots' first album for DGC, Do You Want More?!!!??!, was released in 1994. It was a moderate hit among alternative music fans, boosted by the group's appearance at Lollapalooza. The band performed at the Montreux Jazz Festival that year. Touring guests, beatboxer Rahzel and producer Scott Storch, joined The Roots.  The 1996 release Illadelph Halflife was the group's first album to break the Top 40 on the Billboard 200 chart, spurred in part by MTV's airplay of the video for "What They Do" (a parody of rap video cliches) and "Clones", which was their first single to reach the top five on the rap charts. "What They Do" was also the group's first single to hit the Top 40 of Billboard's charts, reaching a peak of #34. While continuing on the path of live instrumentation, the album's sound was somewhat darker.

IN: Theodore John Kaczynski (; born May 22, 1942), also known as the Unabomber, is an American domestic terrorist. A mathematics prodigy, he abandoned an academic career in 1969 to pursue a primitive lifestyle, then between 1978 and 1995 he killed three people, and injured 23 others, in a nationwide bombing campaign targeting those involved with modern technology. In conjunction, he issued a social critique opposing industrialization and advancing a nature-centered form of anarchism.

At Harvard, Kaczynski lived during his first year at 8 Prescott Street, which was designed to accommodate the youngest, most precocious freshmen in a small, intimate living space. The next three years he lived at Eliot House. One of his suitemates there recalled that he avoided contact with others and "would just rush through the suite, go into his room, and slam the door." Another suitemate said Kaczynski was reserved, but regarded him as a genius: "It's just an opinion - but Ted was brilliant." Other students stated Kaczynski was less socially averse than these descriptions imply; an Eliot House resident who dined with Kaczynski at times called him "very quiet, but personable ... He would enter into the discussions maybe a little less so than most [but] he was certainly friendly."  As a sophomore, Kaczynski participated in a study described by author Alton Chase as a "purposely brutalizing psychological experiment", led by Harvard psychologist Henry Murray. Subjects were told they would be debating personal philosophy with a fellow student, and were asked to write essays detailing their personal beliefs and aspirations. The essays were turned over to an anonymous attorney, who in a later session would confront and belittle the subject - making "vehement, sweeping, and personally abusive" attacks - using the content of the essays as ammunition, while electrodes monitored the subject's physiological reactions. These encounters were filmed, and subjects' expressions of rage were later played back to them repeatedly. The experiment ultimately lasted three years, with someone verbally abusing and humiliating Kaczynski each week. In total, Kaczynski spent 200 hours as part of the study. Kaczynski's lawyers later attributed his hostility towards mind control techniques to this experience. Some sources have suggested that Murray's experiments were part of the US government's research into mind control, known as Project MKUltra. Chase and others have also suggested that this experience may have motivated Kaczynski's criminal activities, while philosopher Jonathan D. Moreno has said that, while "Kaczynski's anti-technological fixation and his critique itself had some roots in the Harvard curriculum," Kaczynski's later bombing campaign can "by no means be laid at Harvard's door".  Kaczynski earned his Bachelor of Arts degree in mathematics from Harvard in 1962. He finished with an above-average 3.12 GPA but had been expected to perform better.
