He sings I'll Be There for You with Jon, TLFR style. He doesn't sing his solo stuff because, in the USA at least, it doesn't get good reactions. I think that's why he stopped singing solo stuff and started singing a band song. Now they're promoting TLFR in addition HAND and the box set. I've seen Richie sing SITT before and it was depressing. Almost everyone either sat down or took a potty break. *I* was standing up for him because I felt sorry for him. Blaze, on the other hand, was a huge hit and everyone sings along with it. It goes over very well. That's why they keep doing it. It's like the song Mystery Train--it's Jon's favorite off Crush but it didn't go over well and they stopped doing it. I think Jon favored Bells of Freedom and it didn't go over well and they aren't playing it every night.
