David Michael Gordon "Davey" Graham (originally spelled Davy Graham) (26 November 1940 – 15 December 2008) was a British guitarist and one of the most influential figures in the 1960s British folk revival. He inspired many famous practitioners of the fingerstyle acoustic guitar such as Bert Jansch, Wizz Jones, John Renbourn, Martin Carthy, John Martyn, Paul Simon and Jimmy Page, who based his solo "White Summer" on Graham's "She Moved Through the Fair". Graham is probably best known for his acoustic instrumental "Anji" and for popularizing DADGAD tuning, later widely adopted by acoustic guitarists.
