Spector's erratic behaviour during the "All Things Must Pass" sessions left Harrison to handle most of the project alone, but in August 1970, after receiving a tape of Harrison's early mixes of the songs, Spector provided him with written feedback and guidance. Spector wrote of "All Things Must Pass", "This particular song is so good that any honest performance by you is acceptable as far as I'm concerned", but he expressed his disapproval of the horns at the start of the track. In the words of authors Chip Madinger and Mark Easter, "clearer heads prevailed" and Jim Price and Bobby Keys' horn parts were retained.
