He lives or lived in Beacon NY.

I would imagine, the post office know where to find him from that.

he did used to write his address in his song books. As apparently it was a cabin he'd pretty much built himself - I don't suppose he's moved. Not really time to build another cabin at his time of life.

I wrote to him about thirty years ago, and he wrote back saying - he was sorry he didn't have time to write a civilised reply and drew a little banjo under his name, and what looks like some Japanese writing.

that was very nice of him.

Its a letter i treasure.
