The lyrics underwent some minor changes after Harrison presented the song to the Beatles in January 1969, when they began working at London's Twickenham Film Studios for the so-called "Get Back" project (released as the "Let It Be" album and film). He had initially written the second line of verse two as the more literal "A wind can blow those clouds away", but bootlegs from the sessions reveal John Lennon suggesting the word "mind" to introduce a bit of "psychedelia" into the song. Similarly, the repeated line "it's not always gonna be this grey" was originally "It's not always been this grey" in verses one and two.
