Charlie O Hegarty was a fixture back in Cambridge MA in the early 70s. Often joining in at Irish sessions at the Plough & Stars to sing a few, or at the infamous Peter Johnson concerts and parties.
This song appears, sung by the author, on the CONCERTINA & SQUEEZEBOX cassette SON OF READER'S TAPE, produced by Joel Cowen in the early 90s.
Last I heard, Charlie had moved to London.
Miss him & wish him well !! riGGy
