I've had the briefest of searches on the forum so this may have been referenced before, and may have been referenced on Blessed State (I have no facebook account so can't post there) but, as the link only seems to have appeared on youtube last year, has only a few views and no comments, this may be new to some people (though not sure how many people still look at this forum)
Anyhow, a 45-minute live set (audio only) from Soft Option (Newman, Simmons, Gray, Gilham) at The Venue, London, March 19, 1981.
