I thought I had it, but the reverse of the Lp, talks about the opening of the Cellar club, not the night or importantly, the date of the Soul Inc Gig.
"Without Fanfare or Publicity there opened in the spring of 1966 in the basement of an old vacant building on East Morehead Street in Charlotte Carolina, a small club aptly names 'The Cellar Club’.
I would say, from the quality of 'WGUMCD' against the rest of the tracks on the Lp, that it's recorded elsewhere and at a different time to the Lp, this is just a guess.
So, Soul Inc form in Sept 1966. I think that there was a recording session of 'WGUMCD' and that was used in the Yellow Emblem single and added to the LP there after.
How does that work?
Not at all, I love threads like this... In fact I think I have come to the same conclusion as you Benji, and Ken has said the same, it was recorded elsewhere, the Yellow 45 and track one/side two on the LP. It has to be.
When? no idea, but late 66 into 67?
re the name change, lots of Soul Inc's out there, and groups that form from other groups do seem to suffer issues with group names.
I think it's likely that this is the issue here, it maybe that the 3 approx years we are discussing was too much without having anything much on the market, or very little. Members leave, and new group forms under a new name, and they have cut an old track.
