recording machine to produce his desired final mix. Wakeman encountered some difficulty with the songwriting as many of the stories described in the books gave different accounts. After reading eight books himself, he picked the details he found the most "colourful" which included taking a passage from a children's book on the subject. He settled on four widely known stories and two lesser known, and proceeded to adapt them to music and lyrics. Much of the album was based around the three swords based around the legend: the sword Arthur pulled out from the stone and anvil, the Excalibur which some believe was instead handed to Arthur by the Lady of the Lake, and the one associated to Galahad. Wakeman incorporated ideas from his personal life into the music, he said: "It's as much about me as Arthur." "Guinevere" was a song that Wakeman had arranged six years prior to recording the album. Wakeman wrote violin arrangements for "Sir Lancelot and the Black Knight" that were so fast for the players, biographer Dan Wooding wrote they "collapsed with laughter" upon viewing the score. After some false starts, they played the music correctly after Wakeman instructed them they play twice as fast as he originally wanted. "I thought I'd teach the ones who were cocky a lesson". "Merlin the Magician" is in three parts; Wakeman had read several descriptions of the character and conjured the image of "a little old man preparing his potions", so he therefore introduces the song with a quiet theme. One book depicted Merlin working in the basement of a castle, "surrounded by bottles and liquids like a mad professor", which inspired the heavier second theme. The piano and banjo section arose from a story that involved Merlin falling in love and chasing after a young girl, who eventually shuts him in a cave where he dies.

The album has sold 12 million copies in total. "Arthur" has been used by the BBC as the theme to its election night coverage from 1979 to 1997, and
