An overly-excited fan decided to bum-rush the stage at a Motley Crue concert and ended up knocking over ailing lead guitartist, Mick Mars. On His 62nd BIRTHDAY no less! Even though the fan was subdued, Nikki Sixx decided to kick him in the head causing actual injury. Mick Mars got back up and after a short break continued the rest of the show with the band. Mick suffers from a nasty condition that gradually fuses his bones together over time. I'm not sure what's more entertaining, the video or the discussion going on right now on YouTube between a guy claiming to be the crazed fan's son and random citizens who don't think too highly of either man.
