Joanie Loves Chachi is an American sitcom television series and a spin-off of Happy Days that aired on ABC from March 23, 1982, to May 24, 1983. It stars Erin Moran and Scott Baio as the characters Joanie Cunningham and Chachi Arcola, respectively. The series was cancelled after 17 episodes, in its second season, due to a drop in ratings. The series is set in the early to mid-1960s and follows the exploits of Joanie and Chachi as they moved to Chicago and tried to make it on their own with a rock band and a music career at a time when the British Invasion was looming (one episode was titled "Beatlemania"). It mixed the traditional elements of a sitcom with musical performances on each show by Baio and Moran; their characters sang to one another in the opening credit sequence of the show. Their backup band consists of a spaced-out drummer named Bingo and Chachi's blasé cousins Mario and Annette.
