Showaddywaddy was a popular 1970s pop group from Leicester, UK. They specialised in cover versions of U.S. pop songs from the 1950s and dressed as Teddy Boys. They sound similar to the American act Sha Na Na. The band was formed in 1973 by the amalgamation of two groups, Choise and The Golden Hammers. This led to an eight member band, with the unusual feature of having two vocalists, two drummers, two bassists and two guitarists. Their first single, Hey Rock 'n' Roll (written by the band), was released in April 1974.
