Finally, I have time to weigh in on this!
Dreamer, we've said it before. Must have been twins separated at birth cause I agreed with everything you said. I especially love the Classic Desperado idea! I think I've mentioned before that I wish Don would just sing and quit being so dramatic with it. If he were drumming that would solve that problem!
SG would be my first choice of Don's songs to go. It is just really dated, imo, boring. ASWTDID is not one of my favorites, but it does really get the crowd going and I'd hate to miss Glenn's performance, but...it could go for Don's new ones. I wouldn't miss HITW one bit!
For Glenn, TITTL is epic (good description), but if he had a new one it could go for me. He must do TS, AG, and HT. PEF, I guess, could go, but I'd miss it alot.
Joe, I can't imagine not hearing LBG or F49. I'd love to hear TTS or OAG. I think Joe needs rockers.
Tim. I'd love to see him do a rocker. I know he can! I'd hate to see him lose any.
