In 1957, a popular television show featuring rock and roll performers, American Bandstand, went national. Hosted by Dick Clark, the program helped to popularize the more clean-cut, All-American brand of rock and roll. By the end of the decade, teen idols like Bobby Darin, Ricky Nelson, Frankie Avalon, Paul Anka, Neil Sedaka, Bobby Rydell, Connie Francis, and Fabian Forte were topping the charts. Some commentators have perceived this as the decline of rock and roll; citing the deaths of Buddy Holly, The Big Bopper and Ritchie Valens in a tragic plane crash in 1959 and the departure of Elvis for the army as causes.
