Wessex Sound Studios 2003.
The Clash and The Damned were both recording at the legendary Wessex Sound Studios in London when this video was shot.
The Damned were working on Machine Gun Etiquette while The Clash were doing the same for London Calling.
The clip captures Captain Sensible, Rat Scabies, Joe Strummer, Topper Headon, Paul Simonon, Mick Jones and producer Guy Stevens enjoying themselves during some downtime.
I believe the footage of Captain Sensible and Rat Scabies in the beginning of the video was shot by Mick Jones.
