From Coil Live at Wiki :
"Experimental music group Coil's live incarnation has a distinct legacy of its own. The initial performances took place in 1983, however they stopped playing live for 16 years after a mere four performances. The first Coil release, a collaboration with Zos Kia titled Transparent, includes a track from the first Coil performance as well as the last 1983 performance. According to the liner notes of Transparent, during Coil's second performance, which was videotaped by Peter Christopherson, John Gosling pees on John Balance. Nick Cave, who was in the audience at the time, promptly left. Marc Almond is also credited for performing that night while Christopherson is only credited for providing back up tapes during the event."
This, then, is the second night's performance. All thanks to Sleazy for permission and F for access.
