The Myths and Legends of King Arthur and the Knights of the Round Table is the third studio album and fourth overall by English keyboardist Rick Wakeman. Released on 27 March 1975 by A&M Records, it is a progressive rock concept album based on the stories and people of the King Arthur legend. It developed in the summer of 1974 while Wakeman was in hospital recovering from a heart attack, and started to write music for it on paper and a cassette recorder. Recording took place during his debut world tour promoting Journey to the Centre of the Earth (1974), and performed some of the album live in Japan, Australia, and New Zealand in early 1975 prior to its release. Wakeman performs with his five-piece band named the English Rock Ensemble, the New World Orchestra, and the English Chamber Choir conducted by David Measham.
