It might make more sense to go to one of Lindsey's concerts and yell support for Lindsey? I'd rather have Lindsey back than the current line-up but I'm not sure yelling Lindsey's name at the band would yield a positive response. I guess it's up to everyone to decide for themselves but I can't imagine the band or people that are there to watch a show would appreciate it.
Maybe don't go and the ticket sales will reflect people's opinions?
