Oldies and Nudies is an instrumental rock song that Alf Clausen wrote that, according to the album it appears on, The Simpsons: Testify, was written for the episode "Homerpalooza". However, according to an interview with Clausen, "[it] was a rock and roll track that I wrote for the end of a Homer party down show, like an Animal House thing, and the producers actually ended up licensing one of the songs from Animal House." So, at the moment, the episode it was written for is not known. But what is known is that it is the final track on the album.
