Having viewed the video and listened again to that beautiful recording of "Girl from the North Country" I have to agree with you WLD. The video does not prove (to me at least) that Dylan is playing on the recording. As to "there's a bit more than that going on", the recorded version is in Bb with capo on 3rd, which changes the colour of the sound, and there's also a hint of stereo/reverb, but the fingerstyle pattern is slightly different too.

When I listen to recordings of, say, Richard Thompson, I am never in any doubt as to who is playing. I have always doubted whether Dylan played on "Don't Think Twice" and a few others. To my ears I get the impression the same guitarist plays these two and "Corrina Corrina" for example.

All this is of no real consequence of course, but interesting nonetheless. I'd love to think guitar anoraks would be discussing my guitar style/playing in 45 years time!!
