Trivia: Fresh from a nondescript Liverpudlian musical group known as Rory Storme and the Hurricanes, Ringo Starr made the quantum leap to superstardom in 1962 when he replaced Pete Best as drummer for the burgeoning Beatles. Starr was regarded by many music aficionados as the least creative of the foursome, though he may well have enjoyed the largest fan following -- especially among young ladies who felt the urge to "mother" the diminutive Mr. Starr (though he appeared to be the baby of the group, Ringo was in fact the oldest of the Fab Four). In the Beatles' first two films, A Hard Day's Night (1964) and Help! (1965), most of the comedy material went to Ringo, whose Chaplinesque demeanor and droll, deadpan dialogue delivery paid off in big laughs. Upon the group's breakup in 1970, it was Ringo who fared best as a solo screen actor. He had already brightened up the dull proceedings of Candy (1968) and The Magic Christian (1970); after the Beatles' split, he was seen to good advantage as the Pope in Ken Russell's Lisztomania (1975), as one of Mae West's bewildered amours in Sextette (1978) and as a bumbling Cro-Magnon in Caveman (1979), in which he co-starred with his second wife, Barbara Bach. In 1973, Ringo produced the bizarre horror movie spoof Son of Dracula, appearing onscreen with fellow rock icon Harry Nilsson. A big draw all over again in the 1980s thanks to his All-Star Band tours, Ringo Starr remains a most welcome, if infrequent TV guest star; he has also shown up in several entertaining commercials, including a 1995 Pizza Hut spot in which he co-starred with ex-Monkees Davy Jones, Micky Dolenz, and Peter Tork. Ringo continued to record music and often appeared in music documentaries, not all of which were about the Beatles. He made memorable contributions to both Who Is Harry Nilsson (And Why Is Everybody Talkin' About Him)? as well as George Harrison: Living In the Material World.

Trivia: Recruited by guitarist Jimmy Page and bassist/keyboardist John Paul Jones to join their post-Yardbirds band in 1968; recommended his friend, drummer John Bonham, to round out the lineup, and Led Zeppelin was born. The band made its recording debut in 1969 with a self-titled album that featured future classics "Communication Breakdown" and "Good Times Bad Times." Released his first solo record, 1982's Pictures at Eleven, two years after Zeppelin broke up in the wake of Bonham's death. Reunited with Page in 1994 for the No Quarter live CD and TV special, which were followed by an album of original material, Walking into Clarksdale, four years later. Inducted into the Rock and Roll Hall of Fame, along with the other members of Led Zeppelin, in 1995. Was made an Order of the British Empire Commander---for "services to Music"---in 2008.

Trivia: An influential figure in new wave rock, Elvis Costello also occasionally appeared in a few feature films such as Alan Cox's bizarre Straight to Hell. Costello has also appeared in concert in documentary films.

Trivia: One of the pioneers of rap-metal music, performer Kid Rock -- a native Detroiter, born Robert James Ritchie -- spent almost a decade toiling in relative obscurity, then shot instantly to global superstardom and multimillionaire status on the basis of his fourth effort, the critically revered 1998 album Devil Without a Cause. From the beginning, Rock also cultivated a very careful and deliberate public image, whereby he promulgated himself as a white-trash rebel steeped in excess; the ploy worked and (in conjunction with his Rock's musical craftsmanship) turned him into a bona fide superstar. On a cinematic level, Rock essayed a quirky series of film appearances beginning in the early 2000s. He debuted as one of the voices in the Farrelly Brothers animated/live-action mix Osmosis Jones (2001), and then took on a supporting role in the gross-out comedy Joe Dirt (2001, as -- what else? -- a white-trash toughie). Aside from a minor role in the action-saturated coming-of-age drama Biker Boyz (2003) , much of Rock's subsequent film work through the late 2000s consisted of guest appearances on such series comedies as King of the Hill and Stripperella. Meanwhile, on a musical level, the performer segued away from rap-metal and toward both Bob Seger-styled rock and gritty David Allan Coe-style outlaw country with equal aplomb; his success as a country & western performer crested with "Picture," a Top 40 duet with Sheryl Crow. All told, this musical genre transition accounted for Rock's presence in the all-star country concert film Jerry Lee Lewis: Last Man Standing (2007).

Trivia: Played softball and rode horses while growing up in Northern California. Was a member of the UCLA coed music group Awaken A Cappella. First solo performance before a large crowd was at UCLA's Spring Sing student talent show. She later toured with Maroon 5, a band with UCLA roots that once played at Spring Sing. Performed in the Kidney Now! skit on 30 Rock's star-studded third-season finale.
