Davy Graham - Cry Me a River
From a BBCTV Ken Russell-directed documentary called Hound Dogs and Bach Addicts: The Guitar Craze …
The then 18-year-old Davey Graham gives a spellbinding jazz performance in a run-down building site, attracting an understandably enthusiastic crowd in the process. This was in fact the film that made Graham’s reputation - he would go on to become one of the leading figures in the following decade’s folk-rock revival.
