Davey Graham is a living legend of the British folk scene. Back in the 1960s, when the folk clubs provided a home for mavericks as well as traditionalists, he was always ahead of the pack, a guitar hero who mixed English folk songs with blues and jazz, and then disappeared to north Africa to add in Arabic influences long before anyone else. He wrote the classic Anji, covered by Paul Simon, and influenced other great players like Bert Jansch. There were fears at one time that his lifestyle would overtake him, but he survived to be rediscovered by the new generation of folk fans.

Davey (or Davy as he was once known), now in his 60s, came on looking like a cool veteran cowboy in black hat and dark glasses. He had confided earlier that "I'm a bit slower than before", but his guitar work was as eclectic as ever. He started with blues, followed by a baroque piece from Serbia and a dance tune from Romania. When asked to sing he responded with Big Bad Bill, the ragtime track recorded by Ry Cooder. Then came his intricate guitar treatment of songs from South Africa, Irish pipe tunes, or a courtly piece from 16th-century Italy.

There were a couple of stumbled passages, maybe, but his playing and musical vision are still unparalleled.

The Spitz devoted the previous night of their Festival of Folk to the Fence Collective from Fife, best known for the songs of King Creosote. They presented a lineup of mostly male singer-songwriters with equally fanciful names. There was Hardsparrow, singing about crab fishing to an inflatable toy crab, and the far less entertaining Gummi Bako adding silly voices to country and gospel songs. Then came the soulful Barbarossa and the sturdy Pictish Trail, finally joined by King Creosote on accordion with a full band for an impressive finale. The free-wheeling presentation was refreshing, but these contemporary mavericks could never match the originality of Graham.
