Some context: Studdard was born in Frankfurt, Germany, to American parents, while his father was stationed there with the U.S. Army, and grew up in Birmingham, Alabama. The youngest son of two teachers, at the age of three, he sang for the first time at the Rising Star Baptist Church in his hometown of Birmingham. He continued singing gospel in church, performing solos as a child while his mother sang in the local choir. While at Huffman High School, he played football for which he received a scholarship to Alabama A&M University.
Studdard joined the cast of fifteenth season of the NBC weight loss competition show The Biggest Loser, and was credited as its first ever celebrity contestant. At 6'3 and 462 pounds, Studdard had the highest starting weight and BMI of the entire cast. A member of the show's Red Team, Studdard was first eliminated in the fourth week after he failed to make his weight loss goal. However, because opposing coach Jillian Michaels had given her team caffeine pills in violation of the rules, Studdard's elimination was voided and he returned before once again being eliminated during the competition's eighth week.  At the show's finale on February 4, 2014 (which coincided with the release of Studdard's newest album, Unconditional Love), it was revealed that he had lost a total of 119 pounds for an ending weight of 343 pounds. Studdard credited the weight loss for improving his ability to perform onstage. During the finale, Studdard also performed his new album's lead single, "Meant to Be", accompanied by the song's cowriter and producer, David Foster, on piano.  Unconditional Love is Studdard's sixth studio album and first with his new label, Verve Records. Foster, who has won 16 Grammy Awards, was the executive producer of the disc, which primarily consists of covers of love songs along with two originals, including "Meant to Be". Studdard has called it "the album that everybody expected from me when I won American Idol." The album features collaborations with Stevie Wonder, Lalah Hathaway, and Eric Benet, and includes covers of songs originally performed by artists such as Paul McCartney, Donny Hathaway, Bonnie Raitt, Marvin Gaye, and Peabo Bryson. Since its release, the album has received some of Studdard's best reviews of his career. According to critics, the album "finds Studdard at the top of his game vocally" and he hits his stride, "exuding grace, confidence and class" as he successfully positions himself as a "stylish crooner." Unconditional Love debuted at #46 on the Billboard 200 and #7 on Billboard's R&B Albums chart.  Studdard prepared for a 2014 tour with his collaborator, Lalah Hathaway, and had planned on releasing a Christmas album at the end of the year.

Some context: Jack Benny - played himself. Protagonist of the show, Benny is a comic, vain, penny-pinching miser, insisting on remaining 39 years old on stage despite his actual age, and often playing the violin badly.

The radio series was one of the most extensively preserved programs of its era, with the archive almost complete from 1936 onward and several episodes existing from before that (including the 1932 premiere). As with the radio shows, most of the television series has lapsed into the public domain, although several episodes (particularly those made from 1961 onward, including the entire NBC-TV run) remain under copyright. During his lone NBC season, CBS aired repeats on weekdays and Sunday afternoons. 104 episodes personally selected by Benny and Irving Fein, Benny's associate since 1947, were placed into syndication in 1965 by Universal/MCA television. Telecasts of the shows in the late evening were running as late as 1966.  Four early 1960s episodes were rerun on CBS during the summer of 1977. Edited 16mm prints ran on the CBN Cable Network in the mid 1980s. Restored versions first appeared on the short lived HA! network in 1990. As of 2011, the series has run on Antenna TV, part of a long term official syndication distribution deal. The public domain television episodes have appeared on numerous stations, including PBS, while the radio series episodes have appeared in radio drama anthology series such as When Radio Was.  Public domain episodes have been available on budget VHS/Beta tapes (and later DVDs) since the late seventies. MCA home video issued a 1960 version of the classic "Christmas Shopping" show in 1982 and a VHS set of ten filmed episodes in 1990. In 2008, 25 public domain episodes of the show, long thought lost, were located in a CBS vault. The Jack Benny Fan Club, with the blessing of the Benny estate, offered to fund the digital preservation and release of these sealed episodes. CBS issued a press statement that any release was unlikely. June 2013 saw the first official release of 18 rare live Benny programs from 1956 to 1964 by Shout Factory. This set, part of Benny's private collection at the UCLA film and television library, included guest shots by Jack Paar, John Wayne, Tony Curtis, Gary Cooper, Dick Van Dyke, Rock Hudson, Natalie Wood, President Harry Truman and the only TV appearance with longtime radio foe Ronald Colman.
