Fat Albert and the Cosby Kids is a animated series created, produced, and hosted (in live action bookends) by comedian Bill Cosby, who also lent his voice to a number of characters, including Fat Albert himself. Filmation was the production company for the series. The show premiered in 1972 and ran until 1985 (with new episodes being produced on an "on and off" basis during that time frame). The show, based on Cosby's remembrances of his childhood gang, centered on Albert (known for his catchphrase "Hey hey hey!"), and his friends.
The show always had an educational lesson emphasized by Cosby's live-action segments, and the gang would usually gather in their North Philadelphia junkyard to play a rock song on their cobbled-together instruments at the end of the show.
