OK, as a very casual VH admirer (always liked their music, but known relatively little about the band) was chatting with a mate tonight, who reckons Roth was that much better than Hagar, the latter's name didn't even deserve a mention so figured I would put it out there to the bigger fans who've followed this band closely (REB IIRC you're one).
Obviously I've since learnt about Cherone, so will leave him out of this.
