well yes....I would say that hand in hand with the trad revival began an abandonment of the time signatures and even the system of scales and keys that were the common currency of the music of the man in the street

remember that bloke, the poet, who didn't believe in chords even.

and really if you look at Carthy's version of Geordie/Georgie - you can see how he got there. MC doesn't play chords he plays notes.

And if you don't play chords - as a guitar player, you're pretty well fucked. Can you follow what I am saying?
