With the recent announcement that the Let it Be film will be re-released, here’s an interesting bit about the three guitar solos on the title song.
The basic take of “Let it Be” was Take 27-A, recorded on 31 January 1969. This was not the version used in the film, which was Take 27-B, recorded immediately after.
On 30 April 1969, George recorded a new guitar solo, wiping the original, though it can still be faintly heard in the background due to mic bleed. This version, Take 27-A with the new guitar solo, would be released as the “Let it Be” single on 6 March 1970.
4 January 1970 would be the last time Paul, George, and Ringo recorded together until the Anthology project twenty-four years later. On this day, Paul recorded a new bass track, removing John’s original bass playing, extra vocal harmonies, percussion, and orchestral overdubs were recorded, and George played an entirely new guitar solo. This version of the song would go on the Let it Be album, released on 8 May 1970.
So, that’s the history of the three guitar solos on “Let it Be,” all of which share the same Take 27-A DNA.
I personally think the album version is superior to the single, but the single is the version more people are familiar with.
