I saw the preview of Julian on the Tonight Show and I wanted to watch it but I fell asleep. I'm sure there's a youtube of him on the show but I didn't have time to search for it and yes, I also thought it was cool that he's still doing music.
Hey, isn't Ringo's son a drummer? Maybe those two should get together and do something.

FYI, I DVR'd a recent concert with Paul and Ringo playing together which is
sooooo cool to see and was an excellent performance.
