Stewart contributed piano, organ, electric piano and/or percussion to all Rolling Stones albums released between 1964 and 1986, except for "Their Satanic Majesties Request", "Beggars Banquet", and "Some Girls". Stewart was not the only keyboard player who worked extensively with the band: Jack Nitzsche, Nicky Hopkins, Billy Preston, and Ian McLagan all supplemented his work. Stewart played piano on numbers of his choosing throughout tours in 1969, 1972, 1975–76, 1978 and 1981–82. Stewart favoured blues and country rockers, and remained dedicated to boogie-woogie and early rhythm & blues. He refused to play in minor keys, saying: "When I'm on stage with the Stones and a minor chord comes along, I lift my hands in protest." In 1976, Stewart stated, "You can squawk about money, but the money the Stones have made hasn't done them much good. It's really gotten them into some trouble. They can't even live in their own country now," referring to band members' tax exile status to minimize tax obligations on their high incomes and royalty payments.
