Lady Madonna "Lady Madonna" is a song by the Beatles, written by Paul McCartney and credited to Lennon–McCartney. In March 1968, it was released as a single, backed with "The Inner Light". The song was recorded on 3 and 6 February 1968 before the Beatles left for India. This single was the last release by the band on Parlophone in the United Kingdom, where it reached number 1 for the two weeks beginning 27 March, and Capitol Records in the United States, where it debuted at number 23 on the "Billboard" Hot 100 for the week ending 23 March and reached number 4 from the week ending 20 April through the week ending 4 May. All subsequent releases, starting with "Hey Jude" in August 1968, were released on their own label, Apple Records, under EMI distribution, until the late 1970s, when Capitol and Parlophone re-released old material.
Sour Milk Sea "Sour Milk Sea" is a song by the English rock singer Jackie Lomax that was released as his debut single on the Beatles' Apple record label in August 1968. It was written by George Harrison during the Beatles' stay in Rishikesh, India, and given to Lomax to help launch Apple Records. The song's recording was the first of many extracurricular musical projects undertaken by Harrison, who produced the track, and a rarity among non-Beatles songs since it features contributions from three members of the band. Along with Harrison, Ringo Starr and Paul McCartney, the musicians on the track were Eric Clapton and session pianist Nicky Hopkins.
