For Atlantic Records' 40th anniversary concert, Jason Bonham, son of legendary Led Zeppelin drummer John "Bonzo" Bonham, was invited to perform with Robert Plant and Jimmy Page. Things did not go as well as hoped. Plant forgot the words to "Stairway to Heaven" and Page's guitar was out of tune. "Thank God Jason Bonham was there," the press declared the following day. "He was the only one who knew the songs!"
[Jason Bonham played a lovable temperamental drummer in Rock Star. "As my wife said, there was no acting involved," he later remarked. "I play an alcoholic drummer."]
