Yep...
You should hear (maybe it would be best not to) the original of Silver Machine
and I'm a fan of that era, grew up on it - a very distracting lady that Stacia... anway, enough drooling, and I've been aware of Mr Angel's site for some years...
SM originally appeared (publicly) on an early Glastonbury LP I once had (just beat the single out but I got it at a later date - very disapointing), but I think it was recorded at the Roundhouse - runs to about 7 minutes and had the late Bob Calvert on vocals, sort of spoken, badly... think yourselves lucky I couldn't find a sample...
