A pair of lusty Motley Crue fans were thrown out the band's 29 January (10) show in Winnipeg, Canada - for making love in the audience.
The couple spent four songs giving fans an eye-popping show as the band performed tracks like Motherf**ker of the Year, but when the unnamed man dropped his trousers, some rock devotees decided they had seen enough and reported the pair to security, who asked the lovers to leave.
Footage of the sex act was captured on a camera phone and was posted on YouTube.com on Monday (08Feb10).
One fan who watched the sex act has written to the Winnipeg Sun newspaper, claiming security "over-reacted" by kicking the couple out of the venue.
He writes, "It looked like a stripper show or something, but it wasn't really all that bad."
