I first heard this played by a guy I was at an induction centre for army recruits with near Birmingham in 1975. He had his guitar with him and he and I played for the lads who were sitting round waiting to be interviewed.
Very hippy dippy, but that's what I was like then.
I did "Don't Think Twice It's Alright" and he did "Mrs Adlams Angels".
He was bloody excellent.
Guys came from all around to hear. I guess they all felt a bit alone, as we did.

Afterwards, a couple of guys came up to us and said "f*ck, if you can play like that, why the hell would you want to join the army?". It was the first actual confirmation that I was making a crap career choice.
