Gong the band

The question is asked but, if the path to the solution is shown, the way to even start on it isn't. The clip is formidable nonetheless.



I had long thought the band to be French; but after some search, it appears Gong was set up by an Australian apparently stranded in France at the time, over visa problems to go to England. The personnel was a mix of French and English musicians over quite a stretch of time, since the 70s.
