Holy Vintyania Trove! A generous Vinty fan in Milwaukee recently sent a small pile of CDs and a video tape. I'm working my way through the goods and will post here as I am able.
Uncle Vinty and the X-Cleavers (c) 1993 Your Uncle's Music BMI except "Roses" and "Where Did Our Love Go."
The CD case has a label, apparently printed on Vinty's old dot-matrix printer. In addition to the copyright notice (reproduced above) and track list is a signed note, in Vinty's hand: "1978 Lost Rehearsal."
Those X-Cleavers appear still to be extant.
