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 . " Run of the Mill " followed soon afterwards , its lyrics focusing on the failure of friendships within the Beatles amid the business problems surrounding their Apple organisation . Harrison 's musical activities outside the band during 1969 inspired other compositions on the album : " What Is Life " came to him while driving to a London session that spring for Preston 's '' That 's the Way God Planned It '' album ; " Behind That Locked Door " was Harrison 's message of encouragement to Dylan , written the night before the latter 's comeback performance at the Isle of Wight Festival ; and Harrison began " My Sweet Lord " as an exercise in writing a gospel song during Delaney & Bonnie 's stopover in Copenhagen in December 1969
