It seems the reason that David Lee Roth didn't perform at the Hall of Fame ceremony is that Velvet Revolver thought the song "Jump" was dumb.
Chicago Tribune | Pop Machine: "'Kinda what happened was, he wanted to sing the song ‘Jump.’ We felt from an artistic standpoint, and I’m being totally honest with you, that it wasn’t a song we felt comfortable with. We don’t have keyboards. To bring a keyboard on stage wouldn’t work for us. We said we’d do ‘Jamie’s Cryin’ ’ or ‘You Really Got Me,’ and he was adamant that wasn’t okay.'"
Drop the artistic integrity bullshit. You were there to be a tribute band. There's nothing lamer than a tribute band.
So just drop all that art crap. You're lame, you suck. Just shut up and play the song that the many you were there to honor wanted you to play.
