This is Bert Jansch's version of Jackson C.Franck's famous tune. It deserves a specific treatment, the particular talent of Bert Jansch bringing fingering subtleties that produce interesting singing variants to other versions. These are not necessarily more complex and we can bet that the late Bert did not consider his version as a difficult piece to play.
