Hi Stefan,
Thanks for your message! I love your web site and looked at it long ago for any evidence of this album. I have the vinyl and have scanned the images of the label which are on Geno's Face Book fan page. It says 77 78/4. The vinyl is 12" but I am unable to play it as the paper sleeve has been glued to it from water damage. I do have the little tape which Doug sent to me but have not have it restored so far.
Take a look at the images on Geno's FB page and let me know what you think.
The album is titled "American Folk Songs". There is an image of the cover which Geno drew.
