They returned to the song briefly towards the end of January, by which time the project had moved location to their own Apple Studio, in central London – one of Harrison's conditions for rejoining the Beatles after his temporary walkout on 10 January. Although the band gave a fair amount of time to "All Things Must Pass", it was ultimately put aside, just as other Harrison compositions including "Old Brown Shoe", "Isn't It a Pity", "Let It Down" and "I Me Mine" received a lukewarm reception, particularly from Lennon. David Fricke of "Rolling Stone" has referred to this period as a "struggle" for Harrison "against the patronizing restrictions of writing within and for the Beatles". Doug Sulpy and Ray Schweighardt, authors of "Get Back: The Unauthorized Chronicle of The Beatles' Let It Be Disaster", observe that Lennon and McCartney routinely rejected Harrison's songs, "even though some were far better than their own".
