Stay the Night would have been perfect, with Oh Love as the second one. I did love "Oh Love" every time it came on the radio, I think it's a great song, too.
I really really hope to hear some of the Trilogy live when they tour!!! I'm dying to hear X-kid, 8th Ave Serenade and/or Lazy Bones. The three best songs on the whole set, IMO. DRB would be really cool, too. Let Yourself Go would be a great opener!
If they do 99 Revolutions I'll die. Yuck. It's the only Green Day song I actively dislike.
