"Crampton Comes Alive" is an instrumental (accordion) solo, not a parody. It is named after the live Peter Frampton album "Frampton Comes Alive".
"Beverly Hillbillies/Miss You" is one song, not two, thus no spaces around the / in the track name. Like "Beverly Hillbillies/Money for Nothing" from his UHF album, this is the Beverly Hillbillies theme song done to the tune of another song, in this case The Rolling Stones song "Miss You".
Tracks 1-3: Sounds like there might possibly be another artist performing with him. Or could just be cast of the show. Not enough info to determine the truth, so leaving it like it is.
