Where are they now?

The photo (a very old one, alas) is of an old friend, Charles Oliver Hegarty. We met when I was living in Nantucket, back in the early 70s. He was singing in a local pub, doing sea chanteys. We always said we were going to get together down the road, but never did. If anyone ever hears of his exact whereabouts, please let me know. I sent a letter to an address in the UK, but never heard back...
