John Renbourn was an English guitarist and songwriter. He was best known for his collaboration with guitarist Bert Jansch as well as his work with the folk group Pentangle, although he maintained a solo career before, during and after that band's existence (1967–1973). He worked later in a duo with Stefan Grossman.

David Michael Gordon "Davey" Graham 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.
