George Martin and his son Giles began work on Love after getting permission from Paul McCartney, Ringo Starr, Yoko Ono, and Olivia Harrison (the latter two representing John Lennon and George Harrison, respectively). In discussing the project, Giles Martin noted that elements were utilized from recordings in The Beatles catalogue, "the original four tracks, eight tracks and two tracks and used this palette of sounds and music to create a soundbed." George Martin also promised a prize to those who could crack a "code" found in the album. Giles Martin said in an interview that he was afraid they wouldn't get the green light to do the project, so he started by making digital back-ups of the original multi-track recordings just to get started on the project. He also said that he and his father mixed more music than was eventually released, including "She's Leaving Home" and a version of "Girl" that he was particularly fond of. Paul McCartney and Ringo Starr, the two surviving members of The Beatles, have responded very positively to the album. McCartney noted that "This album puts The Beatles back together again, because suddenly there's John and George with me and Ringo". Starr commended George and Giles Martin for the album and said that the album is "really powerful for me and I even heard things I'd forgotten we'd recorded."
