Well, it seems some of you have seen them with no problems. I would agree about the singer being the most noticeable, but come on, 4 guys at once gives me pause, plenty of bands have not lived up to former glories after a couple of guys have been replaced. I do agree their style as fairly easily inimitable, so given that with nobody seeming to have any negatives to say about this should allay any concerns! As far as the keys, I'd prefer a live player but it really doesn't bother me if they have to pipe them in, that's just one of those "it is what it is" scenarios...
