 With Norman Kinney as engineer , Harrison recorded the basic tracks for the new songs between 21 April and 7 May 1975 , beginning with " Tired of Midnight Blue " and " The Answer 's at the End " . Among the musicians on the album were many of Harrison 's previous collaborators and associates , including Jim Keltner ( drums ) , Gary Wright ( keyboards ) , Jesse Ed Davis ( guitar ) , Klaus Voormann ( bass ) , and Tom Scott , Jim Horn and Chuck Findley ( all horns ) . Along with Keltner , the most regular participant was a young David Foster , then the piano player in Keltner 's band , Attitudes , while the group 's bassist and singer , Paul Stallworth , also contributed . On what would turn out to be a noticeably keyboard @-@ dominated sound , Leon Russell and Nicky Hopkins made guest appearances as well .
