Vince Neil busted out his homage to strippers, "Girls Girls Girls", but not alongside Motley Crüe -- no, this time he performed it ... with a band of teenagers.
It all went down last weekend during a Crüe afterparty in New Jersey ... where up-and-coming rock trio Going Dark was jamming.
During GD's set, Vince jumped on stage to perform 'Girls' -- and brought along legendary porn star Lisa Ann ... just to burn the moment into the 12, 14, and 16-year old boys' skulls.
Going Dark also got some celeb love when newly crowned boxing champ Sergio Martinez agreed to intro their music video "Stand Up."
Pace yourselves, boys.
