Yeah I know it's quite hard. I'm a singer/bassist myself actually and that high C is quite the biatch to hit for a guy!!

I'm pretty sure it is the exact vocal from the album though, which kind of bothers me. I mean the least he could've done was go into the studio and resing it until it was passable and use THAT to lip synch to. At least that wouldn't have stuck out like a sore thumb in the concert.
