Danny & The Juniors
Danny & the Juniors are a doo-wop quartet from Philadelphia comprising Danny Rapp, Dave White, Frank Maffei and Joe Terranova. Formed in 1955, they are most widely recognized for their hit single "At the Hop", which was released in 1957. They are sometimes erroneously stated as being an Italian-American band (lead singer Danny Rapp was actually of Irish extraction).
