No, Beanster, I don't recall that. I do remember Ellen McIlwaine singing Firehouse Blues at the Main Point and doing a duet with the fire siren across the street. Too bad that wasn't on the radio!
Do you (or anyone) know if Dave Herman is still around? He had a show on WMMR called The Marconi Experiment that was my introduction to what then was called underground music, and he played lots of "folk-rock" and folk-oriented music as well. I think I heard him once on a NYC station a few years later.
Welcome to the Mudcat. Hang out for a while and have a soft pretzel with mustard.
