In addition to Bruce and Southside, Jon's jammed with Daddy Pop (a local Jersey band) more than once. He's joined Bryan Adams, Bruce Willis, and John Mellancamp on stage. I know Jon, and possibly Richie as well, joined Elton John on stage before--Madison Square Garden in the late 80's. He jumped on stage at a bar in Italy and played with the band there while the guys from U-571 were at a bar. Richie played a song with some female artist that was opening for Bon Jovi in 2000 or 2001 in Europe. I have it on video and can't even remember the girl's name or the song! LOL Richie also joined one of the LA based BJ tribute bands. I think it was Bad Medicine, but I'm not sure.

That's all I can remember of at the moment.
