This track is totally over the top, but still incredible:
"In 1978 Patrick recorded an 16 minute long extended Remix version of the song " I Feel Love" performed by Donna Summer . Later, in 1981 , this Megamix was released by Casablanca Records. The Original 1977 version, which was composed by Giorgio Moroder , lasted 8 minutes ."

Donna Summer - I feel love (Patrick Cowley remix)
From this great compilation, of which I will probably be posting much more music.
**Update** I just reposted the remix for the guys over at RVNG
they are putting out a ton of great tunes in the psychedelic/dance/beardo genre. Check em out and blow some of that hard earned cash.
