The Beatles - A Day in The Life: February 16, 1965 (Tuesday)
Studio Two, EMI Studios, London
This second of six consecutive days of EMI began with a 2:30-5:00 pm session that saw "I Need You" and then "Another Girl" completed wit the overdubbing of George's vocal, cowbell and tone-pedal guitar onto "I Need You" and guitar onto "Another Girl".
The Beatles spent the remainder of the session, from 5:00 until 10:00 pm, recording and perfecting in 14 takes "Yes Is Is", and exquisite three-part harmony ballad written by John and sung by John, Paul, and George in a style reminiscent of "This Boy". "Yes It Is" was not selected for the film soundtrack, nor was it included on the non-soundtrack side of what was to become the Help! album, Instead, it appeared merely as the B-side of the Beatles' next single, such as their songwriting wealth.
