But, perhaps we should cut him a little slack, it is the extremely wordy "We Didn't Start The Fire" that he messed up, after all. In the middle of the song, he started to mumble the lyrics a bit before signaling for his band to stop. "Wait a minute, that ain't right. That aint' right," he shouted. "All you gotta do is f*** up one word in that song and it's a train wreck!"

When he suggested skipping the rest of the song and moving on, the audience wasn't having it. "It's the same thing verse after verse!" he protested jokingly. "Just the words change. It's one of the worst melodies I ever wrote!"

Despite his lack of enthusiasm about the song-making us wonder, why the heck he would play it in the first place if he's not impressed-he did finish it, ending it all by joking, "That'll be all over YouTube tomorrow."

Not that he minded, "It's okay. It was an authentic rock and roll f*** up. We're not on tape."
