I don't know if anybody is still following this thread, but I was also a Gloucestermen fan and have, somewhere around the house, a cassette tape of the show because I loved it so much. Yes, it's been a long time!
Back in 2002 I tracked down the singer, Rob Carlson. This was his response:
Dear Brian- Wow. Somebody remembers "The Gloucestermen"! That was my first job out of college. I don't even know if I have a copy. If I do it's buried in a pile of ancient tapes and may not even be playable. I'll take a look, but the odds aren't good.From time to time I've thought of re-recording some of those songs but never did.
FYI- These days I'm doing a comedy/music trio called Modern Man. Our first Album, "The Wide Album, Live at the Bottom Line" has been out for three years and our second will be available soon. Check us out at www.modernman3.com . Thanks for your interest. Best... Rob Carlson
