Prior to touring with the Stones, Keys played with Delaney & Bonnie and Friends with Eric Clapton and George Harrison in 1969. In particular, during the year 1970 he gave an extraordinary series of notable performances. Keys started the year working on Clapton's first solo LP. With Leon Russell, he supported Joe Cocker on the 48-city Mad Dogs & Englishmen tour; the live album Mad Dogs & Englishmen was released later in the year, followed by a concert movie in 1971. During the tour, Cocker and the band were accompanied by a largely American entourage, including a choir, friends, wives, children, groupies and a single dog named Canina; the entire group numbered almost 40 people. After work on George Harrison's All Things Must Pass and more Sticky Fingers tracks, he joined the Rolling Stones for their fall 1970 European tour.
