Question: James Edward O'Keefe III (born June 28, 1984) is an American conservative political activist. He produces secretly recorded undercover audio and video encounters with figures and workers in academic, governmental and social service organizations, purporting to show abusive or allegedly illegal behavior by employees and/or representatives of those organizations. He has been criticized for selectively editing videos to misrepresent the context of conversations and the subjects' responses, creating the false impression that people said or did things they did not. He gained national attention for his video recordings of workers at Association of Community Organizations for Reform

In September 2009, O'Keefe and his associate, Hannah Giles, published edited hidden camera recordings in which Giles posed as a prostitute and O'Keefe as her boyfriend, a law student, in an attempt to elicit damaging responses from employees of the Association of Community Organizations for Reform Now (ACORN), an advocacy organization for 40 years for persons of low and moderate income.  A Washington Post correspondent reported that O'Keefe "said he targeted ACORN for the same reasons that the political right does: its massive voter registration drives", and "Politicians are getting elected single-handedly due to this organization." ACORN mostly registered people from the Latino and African American communities.  The videos were recorded during the summer of 2009 and appeared to show low-level ACORN employees in six cities providing advice to Giles and O'Keefe on how to avoid detection by authorities of tax evasion, human smuggling and child prostitution. He framed the undercover recordings with a preface of him dressed in a "pimp" outfit, which he also wore in TV media interviews. This gave viewers, including the media, the impression that he had dressed that way when speaking to ACORN workers. However, he actually entered the ACORN offices in conservative street clothes (the sleeve of his dress shirt is visible on camera). Furthermore, the ACORN employees involved reported his activities to the police after he left. O'Keefe selectively edited and manipulated his recordings of ACORN employees, as well as distorted the chronologies. Several journalists and media outlets have expressed regret for not properly scrutinizing and vetting his work.  On April 10, 2012, the political gossip site Wonkette reported that Andrew Breitbart had signed a $120,000 contract for "life rights" by O'Keefe and Giles based on the ACORN videos. The contract was paid in monthly increments of $5,000. Giles ultimately received $32,000 before parting ways with Breitbart over what she described in legal depositions as "a conflict of visions". O'Keefe ultimately received $65,000.

Answer: Association of Community Organizations for Reform Now (ACORN),

Problem: Martha and the Vandellas (known from 1967 to 1972 as Martha Reeves and the Vandellas) were an American all-female vocal group formed in 1957. The group achieved fame in the 1960s with Motown. Selected Members of the group were inducted into the Rock and Roll Hall of Fame in 1995. Formed in 1957 by friends Annette Beard, Rosalind Ashford and Gloria Williams, the group eventually included Martha Reeves, who moved up in ranks as lead vocalist of the group after Williams' departure in 1962.

Teenagers Rosalind Ashford and Annette Beard first became acquainted after a local music manager hired them to be members of a girl group he named The Del-Phis. Ashford & Beard, along with then-lead vocalist Gloria Williams, performed at local clubs, private events, church benefits, YMCA events and school functions. They were also being coached by Maxine Powell at Detroit's Ferris Center. One of the group's first professional engagements was singing background for singer Mike Hanks.  The group originally had up to six members, shortened to four. After another member left the group, she was replaced by Alabama-born vocalist Martha Reeves, who had been a member of a rival group, the Fascinations and had also been a member of another group, the Sabre-Ettes. In 1960, the group signed their first recording contract with Checker Records, releasing the Reeves-led "I'll Let You Know". The record flopped. The group then recorded for Checkmate Records, a subsidiary of Chess Records, recording their first take of "There He Is (At My Door)". That record, featuring Williams on lead vocals, also flopped.  Briefly separated, Reeves returned to a solo career performing under the name Martha LaVaille, in hopes of getting a contract with emerging Detroit label Motown. After Motown staffer Mickey Stevenson noticed Reeves singing at a prominent Detroit club, he offered her his business card for an audition. Reeves showed up at Motown on a wrong date (Motown auditions were held at Thursdays, while Reeves showed up to Motown's Hitsville USA studios on a Tuesday). Stevenson, initially upset, told Reeves to look out for clients and other matters. Soon Reeves became Stevenson's secretary and later was responsible for helping acts audition for the label. By 1961, the group, now known as The Vels, were recording background vocals for Motown acts. Prior to her success as lead singer of The Elgins, Sandra Edwards (then going by her surname Maulett) recorded the song "Camel Walk", in 1962, which featured the Vels in background vocals. That year, the quartet began applying background vocals for emerging Motown star Marvin Gaye, singing on Gaye's first hit single, "Stubborn Kind of Fellow" After Mary Wells failed to make a scheduled recording session feigning a short illness, the Vels recorded what was initially a demo recording of "I'll Have to Let Him Go". Motown was so impressed by the group's vocals - and Martha's lead vocals in the song - that the label CEO Berry Gordy offered to give the group a contract. Figuring that being in show business was too rigorous, Williams opted out of the group. With Williams out, the remaining trio of Ashford, Beard and Reeves renamed themselves The Vandellas, after Detroit's Van Dyke Street and Reeves' favorite singer, Della Reese.

Did they work with anyone else?
