I dunno about that last part CDFN... I'm not a huge fan of Mike's voice, he thinks he's a tenor, but his high range sucks. Just listen to his singing on Transatlantic, even on a studio album, it's off key. Meanwhile, go back to "Live Scenes from New York", listen to "Silent Man"... that's Petrucci. That's Petrucci LIVE (they said they didn't do any editing to the DVD version, which I have and has the same vocal take there). I'm sorry, but Petrucci has a great voice, Mike just pushes him out of the way in terms of singing. But I think given a chance, John will do better.
Now, in terms of fan interaction and organization, I'm with you totally.
I can't wait to see what band/project Mike ends up in. I hope he doesn't join another Metal band, actually. I get the feeling that the older he gets, the more of a Beattle he turns into, and I think that's great!
