input: Along with Garcia and second guitarist Bob Weir, McKernan was a participant in the predecessor groups leading to the formation of the Grateful Dead, beginning with the Zodiacs and Mother McCree's Uptown Jug Champions. Drummer Bill Kreutzmann was added and the band evolved into the Warlocks. Around 1965, McKernan urged the rest of the Warlocks to switch to electric instruments. Bassist Phil Lesh joined soon after, and they became the Grateful Dead. The group were keen to involve McKernan in the band, as he was the group's original leader and was considered the best singer and frontman.  The Dead's early sets centered around blues and R&B covers chosen by McKernan. By the end of 1966, Garcia had improved his musical skills and wanted to assert himself more as a leader and musical director, changing the band's direction and reducing McKernan's contributions. In 1967, drummer Mickey Hart joined the Grateful Dead, followed by classically trained keyboardist Tom Constanten in 1968, further changing the group's style. Constanten often replaced McKernan on keyboards in the studio, as McKernan found it difficult to adapt to the new material that Garcia and Lesh composed for the band.  In October 1968, McKernan and Weir were nearly fired from the band after Garcia and Lesh believed their playing was holding the band back from lengthy and experimental jamming. Garcia delegated the task of firing them to Rock Scully, who said that McKernan "took it hard." Weir promised to improve, but McKernan was more stubborn. According to Garcia biographer Blair Jackson, McKernan missed three Dead shows before vowing not to "be lazy" any more and rejoining, while Kreutzmann objected to replacing McKernan and said the event never happened. Following his discharge from the United States Air Force in November 1968, Constanten officially joined the band, having only worked in the studio while on leave up to that point. Road manager Jon McIntire commented that "Pigpen was relegated to the congas at that point and it was really humiliating and he was really hurt, but he couldn't show it, couldn't talk about it." He began to take Hammond organ lessons and learned how to use the various drawbars and controls.  After Constanten's departure in January 1970 over musical and lifestyle differences, McKernan nominally resumed keyboard duties. He contributed instrumentation to only two tracks (Hammond organ on "Black Peter" and harmonica on "Easy Wind", the latter as lead vocalist) on Workingman's Dead (1970), the band's breakthrough studio release. On the follow-up album American Beauty, keyboard parts were handled by Garcia and Lesh, along with session musicians Howard Wales and Ned Lagin. The 1971 live album Grateful Dead featured three overdubbed organ parts from Merl Saunders in addition to McKernan's contributions on "Big Railroad Blues", "The Other One", and "Me & Bobby McGee". While Garcia expressed frustration at McKernan's missed rehearsals and his inability to keep up with new material, Lesh was more forgiving, opining that "it was okay for Pigpen to lay out... we kept wanting Pigpen to be there because he was 'one of us.'"

input: 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.
