were trying to do was create a record that was timeless, so we steered away from using state-of the-art gear. We didn't want to make it fashionable." As with "Free as a Bird", the Beatles worked at McCartney's studio in Sussex, with the intention of producing another single. Added to the demo were the sounds of a double bass (originally owned by Elvis Presley's bassist, Bill Black), Fender Jazz bass guitar, a couple of Fender Stratocaster guitars, one of which was Harrison's psychedelically-painted "Rocky" Strat (as seen in the "I Am the Walrus" video), as well as a Ludwig drum kit. Other than their regular instruments, a Baldwin Combo Harpsichord (as played by George Martin on the Beatles song "Because") and a harmonium (which appeared on the band's 1965 hit single "We Can Work It Out") were also used. During the recording process, it was decided to speed up the tape, thereby raising the key from D minor to E♭ minor. As their sound engineer, the Beatles opted for Geoff Emerick, who had not only worked with them to a great extent in the 1960s, but is often credited with many of the Beatles' audio inventions. The assistant engineer was Jon Jacobs, who had worked with McCartney and Emerick since the late 1970s. The attitude in the studio was very relaxed, according to Lynne: "Paul and George would strike up the backing vocals – and all of a sudden it's the Beatles again! ... I'd be waiting to record and normally I'd say, 'OK, Let's do a take', but I was too busy laughing and smiling at everything they were talking about." Starr said that the lightheartedness was key to ensuring he, Harrison and McCartney could focus on the task: "We just pretended that John had gone on holiday or out for tea and had left us the tape to play with. That was the only way we could deal with it, and get over the hurdle, because [it] was really very emotional." Starr commented: "Recording the new songs didn't feel contrived at all. It felt very natural and it was a lot of fun, but emotional too, at times. But it's the end of the line, really. There's nothing more we can do as the Beatles."
