Bert Jansch and Davey Graham
I stumbled upon this whilst trawling the Youtube files. It’s a rare moment indeed; especially given that neither man is still with us; both having passed away in the last few years (both at a relatively young age, I might add).
Both were greats in their day: exponents of a new approach to acoustic steel guitar playing that fused Blues, traditional and ethnic sounds. Both were from the British Isles.
