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. It reached number two in the UK singles chart. Showaddywaddy then went on to have a further 22 UK hits from this point until late 1982. The first few singles were all written by the band and these generally reached the top-20. However they had most of their biggest hits with pop versions of old '50s US rock 'n' roll songs, catchy tunes backed up by their colourful image, dance routines and numerous television appearances. Some of their best known covers are Three Steps To Heaven, Heartbeat, Under The Moon Of Love, You Got What It Takes, Blue Moon (based on the Marcels' interpretation), and I Wonder Why. In total they had ten Top Ten singles, a Number One, and spent 209 weeks in the UK singles chart. At the peak of their popularity, this tally included having seven successive Top Five entries. Their biggest selling single was the aforementioned "Under The Moon Of Love", which sold 985,000 copies and gave the group its only UK Number One.
