Can you send us the pictures or post them somewhere? That would help

Exactly my thought. If there's a way for you to post any of your
photos on the web somewhere, it's quite likely somebody on the list
could indentify the band... unless, of course, it was a local outfit
who never recorded.
Additionally, if nobody on Harp-L knew the answer, I would be happy
to run a link to the photo(s) to some of the other (more specifically
blues history) lists...
