akin to the Band, a suggestion that resulted in Lennon switching from guitar to Lowrey organ, a keyboard favoured by the Band's Garth Hudson. During the Twickenham rehearsals, the Beatles also discussed the idea of Harrison performing "All Things Must Pass" solo for inclusion in the proposed film. 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". The Beatles never formally recorded "All Things Must Pass", and only rehearsal takes circulate on bootleg compilations from the sessions. The Fly on the Wall bonus disc accompanying the McCartney-instigated Let It Be... Naked album (2003) includes a snippet of the Beatles indulging in some Band-like chorusing on the song. Harrison's solo demo During the Beatles' Apple Studio session on 28 January, Harrison talked with Lennon and Ono about possibly doing a solo album of his unused songs, in order to "preserve this, the Beatle bit, more". Lennon offered his support for the idea. While author Bruce Spizer has suggested that Lennon was keen to "spare" the band from having to work on Harrison's songs, Sulpy and Schweighardt consider that Lennon's enthusiasm was because such a solo project would allow him and Ono to continue their own recording activities "without causing friction within The Beatles". On 25 February 1969, his 26th birthday, Harrison entered Abbey Road Studios alone and recorded a demo of the song, along with other recent compositions "Old Brown Shoe" and "Something". With Ken Scott serving as engineer, he recorded two takes of "All Things Must Pass", adding extra electric guitar onto the second. This version was
