I would sign a petition to drop both Got the Time and Antisocial. However, I also think that the songs work quite well live, but I still want them dropped because a) they are covers & b) I'm sick and tired of them. On the other hand, I think that they should drop Only as well, as it doesn't work live with Joey on vocals and it sort of drags down the pace and intensity of the rest of the set. I was at an Anthrax show this summer (a festival in Norway) and my girlfriend was there too. She hadn't seen Anthrax before and didn't know too much about the band or their music and when I asked her what she thought of the show, she said she enjoyed it all the way through, apart from that one song that was kinda boring and brought down the mood a bit. No prizes if you've guessed it: she was talking about "Only" ... It just doesn't fit in anymore & it certainly doesn't work anymore.
So, for my own selfish reasons; get rid of Got the Time, Antisocial and Only (put in Gung Ho or just about anything from worship music, dammit!)
For musical reasons and to pander to the casual fan: get rid of Only ...
