Holy sweet jesus I hope LP never plays Not Alone live. Please no, lol. Definitely not interested in seeing that one live. I believe it'd get really old after seeing it 2-3 times due to how repetitive/slow it is.
New Divide brings the place down live, that is a great great live track. I would predict that LP might even open with New Divide in 2010...it's really solid live. Chester will eventually get on par with the vocals but unless you're listening to a recording of it, I think you don't really notice that at all live.
Across The Line is one of my favorite LP tracks ever made. I'd love to hear it live but I think the chances of LP playing both Across The Line and Blackbirds live are slim due to the fact that they'll want to play all their previous singles and new songs live. Mike even said something in an LPU chat like that they need to play as many singles as possible live. Ouch, lol.
I think a nice setlist with a few singles from each album, a few new songs, a song from the HTEP, an LPU CD song and either ATL or Blackbirds would be cool. I WOULD say I'd support Not Alone replacing Numb or Somewhere I Belong in the setlist due to hearing those so many times live...BUT I think I would regret that after a few shows lol.
