Theme to Happy Days (Happy Days)
Bill Haley and His Comets recorded a new version of their hit "Rock Around the Clock" for the theme song of the show about the middle-class Cunningham family and their life in Milwaukee in the 1950s and 1960s. After two seasons, the song "Theme to Happy Days," composed by Charles Fox and Norman Gimbel and performed by Truett Pratt and Jerry McClain, moved from the show's closing song to the opener. The song was released as a single in 1976 and cracked Billboard's top five. The final season of the show featured a more modern version of the song led by Bobby Avron, but it was unpopular with fans.
