Using A&M Studios in Hollywood as his base for the next three weeks, Harrison rehearsed on a sound stage with his tour band, which, along with Scott, Preston, Weeks and Newmark, included L.A. Express guitarist Robben Ford, Harrison's Concert for Bangladesh horn players Jim Horn and Chuck Findley, and jazz percussionist Emil Richards. Harrison's drummer of choice, Jim Keltner, also participated, but he would not join the tour until late in November. Aside from the Harrison material, selections by Preston and Scott were also rehearsed for their spots in the show, since, as at the Bangladesh benefits in 1971, Harrison was keen for other artists to have their moment centre-stage. In a fusion of musical cultures, Harrison, Scott and Richards rehearsed with Shankar's orchestra for some of the Indian-music pieces, and all the musicians, Western and Indian, came together for the "Shankar Family & Friends" tracks "I Am Missing You" and "Dispute & Violence".
