A band possibly as covernut as me would have been Mr.Big. When you listen to their Live cd, before they start The Who's Baba O'Riley, you hear Eric Martin say "Stop the band" and they start into the first 30 seconds of Van Halen's Ain't Talking Bout Love. Paul Gilbert once explained in an interview that this is actually a game the band usually play in rehearsal. Someone calls out and starts into a coversong, the rest of the band is to pick up which song it is and join in. Considering the background of the musicians in the band, the diversity must have been enormous!

A quick check. Mr.Big have recorded covers of The Who (Baba O'Riley), Cat Stevens (Wild World), Free (Mr.Big) and Deep Purple (Woman From Tokyo). Guitarist Paul Gilbert really was the cover monster of the band. In his solo work he covered Johan Sebastian Bach, Spice Girls, Donna Summer, Jimi Hendrix and ABBA, while his adventures with his current band Racer X had him do Kiss, Blue Oyster Cult, Black Sabbath. And I might be forgetting a few!
