"blue" Unreleased Track ?

[Simon T]

I remember seeing an acetate years ago with just the word 'blue' written on. I think Pat Brady played it out as Jerry Cook - Since I Lost My Baby. Anyone know anything more about it? Was it ever released?

Blue Since I lost My Baby with My World on the flip. Saw what I believe was Pat's old copy with Jerry Cook written on the label I think last year sometime. Only on the acetate as far as I know with no issue.

Pretty certain it is an acetate only, have the full version on a tape somewhere from years ago along with a load of new discoveries, as was then. Will dig it out and see if I made any more notes on the cover (as i am prone to do when I get more info on things)
