Dark Horse is the fifth studio album by English musician George Harrison, released on Apple Records in December 1974 as the follow-up to "Living in the Material World".
 Although keenly anticipated on release, "Dark Horse" is associated with the controversial North American tour that Harrison staged with co-headliner Ravi Shankar in November and December that year.
 This was the first US tour by a member of the Beatles since 1966, and the public's nostalgia for the band, together with Harrison contracting laryngitis during rehearsals and choosing to feature Shankar so heavily in the program, resulted in scathing concert reviews from some influential music critics.
"Dark Horse" is a song by English musician George Harrison, released as the title track to his 1974 solo album on Apple Records.
 The song was the album's lead single in North America, becoming a top-twenty hit in the United States, but it was Harrison's first single not to chart in Britain when issued there in February 1975.
 While the term "dark horse" had long been applied to Harrison due to his success as a solo artist following the Beatles' break-up in 1970, commentators recognise the song as Harrison's rebuttal to a number of possible detractors: those reviewers who criticised the spiritual content of his 1973 album "Living in the Material World"; his first wife, Pattie Boyd; and his former bandmates John Lennon and Paul McCartney.
 Harrison also used the title for that of his record label, and his 1974 North American tour with Ravi Shankar would come to be known as the Dark Horse Tour.
