First up, the theme song to 1979 Animal House rip-off King Frat (aka King *@#!! Frat). Not sure who performed or wrote this. Possibly film composer Red Neinkirchen. Anyways, watch out for butts.
Next, here’s Craig Sheffer lip-syncing to “Nature of the Beast” sung by Paul Revere & The Raiders frontman Michael Bradley in the movie Voyage of the Rock Aliens.
