The path of Let It Be was somewhat tortuous. In April 1969, the single "Get Back" with "Don't Let Me Down" was released. Then, engineer Glyn Johns prepared a version of the album, which would be called Get Back, but the band rejected it. The material was put on hold while they recorded Abbey Road. It was in January 1970, after the departure of John Lennon, that tracks like "Let It Be" and "I Me Mine" were completed, the latter with the production of George Martin. When the idea of the documentary film was revisited, Lennon and Harrison enlisted producer Phil Spector to assemble the album. Spector made decisions such as incorporating a 1968 take of "Across the Universe" and adding orchestral and choral arrangements to several songs, something that did not convince Paul McCartney, especially on "The Long and Winding Road".
Despite the complications in its creation, Let It Be reached the top positions on the charts in several countries. In 2003, McCartney spearheaded Let It Be... Naked, a version without Spector's additions and with a different track order. And in 2021, an expanded and remixed edition was released, coinciding with the documentary series The Beatles: Get Back, which revisited the January 1969 sessions and the rooftop concert. The album, officially released on May 8, 1970, is remembered as the Beatles' last studio album.
