Didn't JLB and Jordan do it once? Might not be a whole band thing, but there's video of James and Jordan playing it to a small group.
Yeah, but that's why it might have been different. Because it's not like, "We're Dream Theater and this is our song, bitch." It was pretty much just the vocalist from that particular line up, and Jordan could have performed it as an homage to Kevin Moore more than "A Dream Theater Song."
I don't know, I mean, I wasn't there, so I don't know how they decided to do it, but I'm pretty sure that if it was the whole band, and JP had any say in it, he wouldn't have wanted to perform it.
