30 years ago this week, Aerosmith played one of their most famous gigs ever - Moe's Tavern on The Simpsons.
On Nov. 21st, 1991, the band appeared in the classic episode "Flaming Moe's" - at a time when celebrity guest stars will still be relatively new to the series.
Three decades later, dozens of rock stars have appeared on the show - including the Rolling Stones, Red Hot Chili Peppers, Metallica, and three out of four Beatles.
