In September 1967, Scott was promoted to Engineer, where his first session was with The Beatles on their song "Your Mother Should Know". His first orchestral recording session came a few days later when he recorded the strings, brass and choir for the band's song "I Am the Walrus". During his time with The Beatles, Scott also worked on the singles "Lady Madonna", "Hello, Goodbye" and "Hey Jude", as well as The Beatles (the White Album) and Magical Mystery Tour albums. Among the notable songs from those albums that he worked on are "The Fool on the Hill", "Glass Onion", "Helter Skelter", "Birthday", "Back in the U.S.S.R.", "While My Guitar Gently Weeps" and "Not Guilty", the last of which was recorded for the White Album, but not included on it.
