WORLD WILDLIFE FUND VERSION
During the February recording sessions comedian Spike Milligan visited The Beatles in studio. Upon hearing Across the Universe he thought the song would be ideal for release on a charity album he was working on for the World Wildlife Fund.
The Beatles later agreed to Milligan’s proposal and in January of 1969, the best mono mix was chosen and remixed for Milligan’s charity album.
This version was released on No One’s a Gonna Change Our World on December 12th 1969, and also appears on the Past Masters and Mono Masters singles albums.
LET IT BE VERSION
During the Let It Be sessions in January of 1969 The Beatles began working on the song again – John Lennon can be seen performing the song in the Let It Be documentary film. The band decided it should be released on their forthcoming Let It Be album.
When Phil Spector was enlisted to produce Let It Be in 1970, he went back to the February 1968 recording of Across the Universe, remixed it and added orchestral and choral overdubs to the track. Spector also slowed the track down to near its original speed.
