Dion and the Belmonts

Dion and the Belmonts were a doo-wop group popular in the fifties. They had several hits late in the decade, with Dion going solo in 1960 and having lingering success until 1964 and the rise of The Beatles. Only Dion was inducted into the actual Hall of Fame, without the Belmonts. There was a special committee many years later which inducted neglecting backing groups such as The Comets and the Crickets, but the Belmonts were not included.
