In defense of my 'conspiracy' I suggest you listen to 12/04/01. Danny Phipps of the Joel cover band Glass Houses calls in at about 1:26, he even explicitly references a fellow BJ cover band that only plays his music form the 90s. 80's Billy Joel Doo Wop Sucks
I recently saw the movie Step Brothers. Did anyone else find the Billy Joel cover band to be treading on familiar territory?
