Oh yeah, one more thing:

I read or heard somewhere that the guitar player singing on the staircase during the "Animal House" toga party ~ upon whose head Beluschi busts his guitar ~ was none other than Chicago folk icon Steve Goodman.

I'm familiar with some of Steve's songs and know him by name and reputation, but never saw him in person and am not really able to recognize his face. Can anyone verify (or disprove) that he indeed played this tiny but very memorable cameo part?
