Last winter we rummaged through the porn parody vinyl racks for a couple weeks. Among our finds: two Caballero 1980s flicks called Dark Side of the Moon and House of the Rising Moon.
Caballero finished the trilogy with A Total Eclipse of the Moon in 1987, now reissued on DVD. The cast includes Gail Force (on the box cover), Tiffany Storm, Purple Passion and FM Bradley.
No porn company can afford to license actual Pink Floyd songs, but if you hit play on Dark Side of the Moon right when the XXX flick starts, you get all sorts of spooky parallels. Probably.
