Ok, I can only base this on a record from video of recent Leppard shows, but Joe Elliot has nowhere near the stage pressence of JBJ. Vocal-wise they both struggle, and Joe does still hit the high notes better than Jon, but as far as stage movements, crowd interaction, and overall stage pressence, Jon totally owns Joe from what I've seen.
Now, I'm a Leppard fan, and I was supposed to see them this summer but couldn't at the last minute. Now, I'll def see them next time they come around, and see if I'm totally riht.
