Anonymous comment to JGMF "I was at the dead show on 11 30 68 cincy hyde park teen center. I passed out posters for Jim Tarbell around town{ I even have a couple of these rare buggers left,if any body is interested} The poster says two shows one at 7:30 the other at 10.But I also remember that there was a show for hyde park community center members only on the day before or after, cant remember."
