The Ghetto Avenue Boys

From the "Something You Can Do With Your Finger" episode (07/12/2000) of animated Comedy Central show South Park.

Stan's dad, Randy Marsh, gets upset when his son wants to join a boy band, because he himself quit high school to be in this boy band. After a short time at the top (looks to be the early/mid 1980s), he and the other four members he doesn't even know get thrown over by their producer for a new group he's put together, The Avenue Ghetto Street Boys. Randy quickly crashes and burns, and penniless, comes crawling back home.
