42 years ago, I received this hand painted invitation to a free festival in the ruined gardens of Rivington Pike near Chorley in Lancashire. I knew I still had it but it had gone missing and I'd been searching for it for 15 years at least. Yesterday it fell out of a bunch of old papers and yellowed copies of International Times.

There's a detailed write up here of the adventures we and others had.

There's a postscript as well. Here And Now liked my write up so much, they asked me to do the liner notes for one of their Live CDs of their set at the festival.
