Possibly the stoopidest rock & roll porn parody ever was Sgt Pecker’s Lonely Hearts Club Gangbang.
There are four female pornstars — the notorious Annabel Chong, Jordan Lee, Kerri Downs and Sylvia Ryder — which makes this more of an “orgy” than a “gangbang”. The male cast includes Dick Nasty, Guy DiSilva, Ron Jeremy and Tom Byron.
