Just watched Murray Lerner's film 'The Other Side Of The Mirror' from BBC4 last night - it documents Dylan's 1963 and 1965 Newport folk festival appearances.

Although it's always being raided for clips, I'd never seen the full film before and it stunned me into realising (remembering?) what an incredible artist the pre-electric Dylan was - just acoustic guitar, harp and voice

Appropriately for today, there's a song with Johnny Cash as well
