written by George HarrisonGeorge Harrison – vocals, electric guitar, acoustic guitar, Hammond organEric Clapton – lead guitarNicky Hopkins – pianoPaul McCartney – bassRingo Starr – drumsJackie Lomax - backing vocalsGeorge Harrison provided this song to Jackie Lomax, who made he debut on the Apple label.The recording featured an extremely powerful lineup of George Harrison, Paul McCartney, Ringo Starr, Eric Clapton, and Nicky Hopkins.George himself is also in charge of producing.　Eric Clapton's guitar that drives throughout the song and Nicky Hopkins' piano that gets into the zone give the song a powerful vitality.I like that it has the sound and feel of a song from the "White Album" because three members of the Beatles are participating.June 26, 1968After finishing the final recording of "Sour Milk Sea" at Trident Studios in London, George, Paul and Ringo returned to their home base, Abbey Road Studio 2, and joined up with John Lennon.(John had been finishing up "Revolution 1" and "Revolution 9" until the day before.)They have started recording John's powerful new song “Everybody's Got Something to Hide Except Me and My Monkey.''The recording of "Sour Milk Sea" also influenced the Beatles. After this, Nicky Hopkins participated in "Revolution".Eric Clapton participated in “While My Guitar Gently Weeps”.In particular, his connection with Eric Clapton was a great support for John when he later formed the Plastic Ono Band.Ironically, this also became one of the supports that solidified John's decision to leave the Beatles.
