How about Good Habit. They performed in monk's habits. I don't think they ever got a recording contract.

I used to go to the Albemarle Youth Club in Harold Hill near Romford, Essex. The biggest bands there were:

Fusion Orchestra, Man, Stackridge, Supertramp (whatever happened to them after the youth club years),

Also
Gong, Egg, Kilburn and the High Roads, Ten Years After, Can, Camel, Morgan, Tangerine Dream, Kraftwerk
