Karma!" This association led to Spector being given the task of salvaging the Beatles' Get Back rehearsal tapes, released officially as the Let It Be album (1970), and later co-producing All Things Must Pass. Harrison first discussed the possibility of making a solo album of his unused songs during the ill-tempered Get Back sessions, held at Twickenham Film Studios in January 1969. On 25 February, his 26th birthday, Harrison recorded demos of "All Things Must Pass" and two other compositions that had received little interest from Lennon and McCartney at Twickenham. With the inclusion of one of these songs – "Something" – and "Here Comes the Sun" on the Beatles' Abbey Road album in September 1969, music critics acknowledged that Harrison had bloomed into a songwriter to match Lennon and McCartney. He began talking publicly about recording his own album from the autumn of 1969, but only committed to the idea after McCartney announced that he was leaving the Beatles in April 1970.

He co-wrote at least two songs with Dylan while in Woodstock, one of which, "I'd Have You Anytime", appeared as the lead track on All Things Must Pass. Harrison also wrote "Let It Down" in late 1968. He introduced the Band-inspired "All Things Must Pass", along with "Hear Me Lord" and "Let It Down", at the Beatles' Get Back rehearsals, only to have them rejected by Lennon and McCartney. The tense atmosphere at Twickenham fuelled another All Things Must Pass song, "Wah-Wah", which Harrison wrote in the wake of his temporary departure from the band on 10 January 1969. Harrison later confirmed that the song was a "swipe" at McCartney. "Run of the Mill" followed soon afterwards, its lyrics focusing on the failure of friendships within the
