The song was written for McCartney’s daughter Beatrice when she was two years old. The video for the song was directed by Marco Sandeman.
McCartney began work on ‘222’ in mid-2006, but it was reworked in early 2007 at RAK Studios.
In addition to appearing on the deluxe edition of Memory Almost Full, it was included in The 7″ Singles Box. The 2002 box set contained a previously-unreleased single – ‘Nod Your Head’, with ‘222’ on the b-side.
