I'm not in a cover band anymore but I was just watching some old vids and couldn't help but notice songs that were not up to par. The worst butcher job we did was a version of 25 or 6 to 4. Way too fast, a guitar doing the main horn section riff and guys singing that should NOT have attempted those vocals. Sure was fun to wank leads on though! Just havin some fun, what songs did your band ruin??
