George and Eric and the guitars". Molland recalled that, to achieve the resonant acoustic guitar sound on songs such as "My Sweet Lord", he and his bandmates were partitioned off inside a plywood structure. According to Voormann, Harrison set up a small altar containing figurines and burning incense, creating an atmosphere in which "everyone felt good." Having suffered in the Beatles at McCartney's tendency to dictate how each musician should play, Harrison allowed the contributors the freedom to express themselves in their playing. All the participants later recalled the project favourably. The first song recorded was "Wah-Wah". During the playback, Harrison was shocked at the amount of echo Spector had added, since the performance had sounded relatively dry through the musicians' headphones. Voormann immediately "loved" the sound, as did Clapton; Harrison later said: "I grew to like it." "What Is Life", versions one and two of "Isn't It a Pity", and the songs on which Drake participated, such as "All Things Must Pass" and "Ballad of Sir Frankie Crisp", were among the other tracks taped then. Preston recalled that Spector's approach was to have several keyboards playing the same chords in different octaves, to strengthen the sound. Preston said he had reservations about this approach but "with George's stuff it was perfect." According to White, a "really good bond" formed among the musicians; the main sessions lasted three weeks and "There was no mucking around." Badfinger participated in five sessions until early June, when they left for an engagement in Hawaii. Molland said they would record two or three songs each day, and that Harrison ran the sessions, rather than Spector. Wright recalls that as the project progressed, the large cast of musicians was pared down. He says that the later recording sessions featured a core group of himself, Harrison, Clapton, Starr or Gordon on drums, and Voormann or Radle playing bass. The Apple Jam instrumentals "Thanks for the Pepperoni" and "Plug Me In", featuring Harrison, Clapton and Mason each taking extended guitar solos, were recorded later in June, at the Beatles' Apple Studio, and marked the formation of Clapton, Whitlock, Radle and Gordon's short-lived band Derek and the Dominos. Harrison also contributed on guitar to both sides of the band's debut single, "Tell the Truth" and "Roll It Over", which were produced by Spector and recorded at Apple on 18 June. The eleven-minute "Out of the Blue" featured contributions
