Motley Crue's Vince Neil Takes Swing At Fan

TMZ has obtained video of the Motley Crue singer taking a closed-fist, rage-fueled swing at a front row concert-goer during a show in New Mexico over the weekend.

Neil had just started performing "Kickstart My Heart" when the fan did something that angered him. Vince stopped the song and started yelling at the guy to "get the f--- outta here!"

When the guy started getting mouthy back at Neil, the singer reached back and tried to punch the man in the mouth ... but the fan ducked ... and Neil totally whiffed.
