Stevenage 1965, A one day, one off, festival. And get the lineup!
The few I remember were;

Bill Monroe & the Bluegrass Boys
Bill Clifton & the Echo Mountain Boys
Tom Paxton
Derek Brimstone
Rick Norcross
I think there was a group from up north. The Tannahill Weavers springs to mind.
and some old dude in a cowboy suit who played Country on guitar and one of those miniature harmonicas that you hold inside your mouth!

That day changed my whole outlook on music!

Oh, and Bill Monroe played a request for me (The Orange Blossom Special)
