Many Thanks ...much appreciated
What you see is what you get, that's all of Flynn's, every single one up to the present.
If you go to BrucebaseWiki and click on Recording Sessions. Listed are plenty of Studio Bootlegs, if not all. eg: Click on Recording Sessions, Click on the Album of Choice, in this case WIESS, Scroll down past the overview and official release info to 'DETAILS' Next to each song you'll find abbreviated bootlegs listed in bold blue font. Click on it and you'll see the boots those studio tracks are on.
I hope this helps.
