From what I remember, they've already played all the big crazy songs this year that they did last year (Damned, STBI, etc). A lot of the other stuff was less great stuff like IGTG, Garageland, Story of My Life, and others.

I think (It's Hard) Letting You Go can happen. It's easy enough to sing, and it's a gorgeous song that obviously Jon knows how to do after last year. However, I'd rather he doesn't reach the mark rather than getting to the 72 songs with songs like Compicated.
