groups (Flash Cadillac, Showaddywaddy, Big Daddy), as well as the Broadway musical Grease (and its feature film adaptation), the feature film American Graffiti and the TV show Happy Days. Before 1969, the group had been singing as part of the long-standing Columbia University a cappella group called the Columbia Kingsmen. But when, based on Leonard's advice, they transformed their show and became a commercial act, they changed their name to Sha Na Na, due to the Pacific Northwest group also called The Kingsmen that had become famous for recording the 1963 hit "Louie Louie". At the time when the group was being transformed from the Columbia Kingsmen into Sha Na Na, George Leonard's brother, Rob Leonard, was one of the group's bass singers and its official leader. Rob Leonard's performance at Woodstock of "Teen Angel", a teen-tragedy classic from 1959 to 1960, was later included in the 2009 Director's Cut of the Woodstock movie. The group's first manager, Ed Goodgold, had codified trivia as a nostalgic quiz game and conducted the nation's first trivia contests with Dan Carlinsky in 1965. The future Sha Na Na/Kingsmen were featured singers at these contests. Four years later, he co-authored "Rock 'n' Roll Trivia" just as he and the William Morris Agency began steering Sha Na Na's career. From 1969 until 1971, the band played at, among other places, the Fillmore East and Fillmore West, opening for such bands as the Grateful Dead, the Mothers of Invention, and the Kinks. When Sha Na Na began headlining at other venues, one of their opening acts was Bruce Springsteen. In 1972, Sha Na Na was one of just four acts invited by John Lennon and Yoko Ono to perform with them at their One-to-One benefit concert at Madison Square Garden. Subsequently, the group appeared in the 1978 movie Grease, and, from 1977 to 1982, the group reached perhaps the height of its success with its own hit syndicated television show Sha Na Na, featuring guest musicians such as James Brown, the punk rock band the Ramones, Chuck Berry, Little Richard, Bo Diddley, the Ronettes, and Chubby Checker. The original band line-up featured 12 performers: Robert A. Leonard (Rob Leonard) (bass vocals), Alan Cooper (bass vocals), Frederick "Dennis" Greene (Denny) (vocals), Henry Gross (guitar), Jocko Marcellino (drums), Joe Witkin (piano), Scott Powell (also known as Captain Outrageous and Tony Santini) (vocals), Donald "Donny" York (vocals), Elliot "Gino"
