From CNN.com:
Only Van Halen’s second lead singer, Sammy Hagar, and ex-bass player Michael Anthony turned up for their induction. Guitarist Eddie Van Halen has just gone into rehab and original lead singer David Lee Roth stayed away in a tiff over what he would perform.
From Billboard.com:
“Velvet Revolver performed in place of Van Halen and without Roth. Frontman Scott Weiland explained the ensuing controversy: “We were asked to perform. 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.”
Dear Scott Weiland – you don’t get to tell David Lee Roth what song he sings at his Rock N Roll Hall of Fame induction!!! You haven’t earned it! You are a pathetic junkie – a junkie who should be down on his knees every hour, thanking God that he gets to be in a band with Slash. When Diamond Dave says “Jump”, you say, “How loud?”
