Thanks Greg. Nitroboy - the footage was shot by Czech/American musician Ivan Kral (Blondie / Iggy Pop / Patti Smith / David Bowie ....). A few years ago he posted this short sample on his youtube channel in low quality with a huge watermark, originally he claimed the full footage is about 3 minutes long, later he claimed the short bit is all he filmed and even later he completely removed it from youtube, I wonder why
