In Search Of Clarence's Magic Garden

You'd think everywhere was somewhere on the internet, wouldn't you? An article, a photograph, a reference, a reminiscence ... something. Yet the only mention of Clarence's Magic Garden I can find is ... right here.
Clarence was an old man back in the 'sixties, a primitive/naive (horrible terms) artist I've likened to Moondog. Not a musician, a sculptor. He created a world of his own in New York State, I think up near Woodstock, a garden of strange houses and weird forms, wrapped in tinfoil and studded with found objects, dolls, glittery trash. You can see a glimpse of it on the cover of the Jake And The Family Jewels album, and it gets a credit in the liner notes. I also remember it being featured in an art book I owned. But according to the internet, it never happened. Just bubbles of false memory foam.

I contacted an old friend of mine (hi, Joel!) who lives up in the backwoods close

to the Catskills and the site of the festival, and asked him if he knew anything about it. He's busy right now painting psychedelic signs for the 50th anniversary, but nope, he can't recall anything about Clarence's Magic Garden.

A magical little corner of the world, lost in time and place. A secret from the internet. Maybe that's a good thing.

EDIT: Note exactly a secret! A helpful comment from the most hardworking presence on the internet - Mr Anonymous - clears up the mystery.
