Liverpool Sound Collage is an ambient electronic album by Paul McCartney, which is also credited to The Beatles, Super Furry Animals, and Youth.
McCartney had previously released two projects with Youth under the moniker The Fireman.
Because McCartney was so heavily involved in its creation, in addition to his production credit, "Liverpool Sound Collage", which was released in 2000, is generally considered a part of his main discography and is filed under his name.
Asked by artist Peter Blake to create something musical and with a Liverpool spirit to it, in order to complement his concurrent artwork exhibition, McCartney ended up harking all the way back to session chatter by The Beatles (hence their "involvement") and using snippets of his 1991 classical piece "Paul McCartney's Liverpool Oratorio".
He also can be heard walking the streets and asking various pedestrians to give their impressions of Liverpool and The Beatles.
"Liverpool Sound Collage" was nominated for the 2001 Grammy Award for Best Alternative Music Album.

McCartney wrote the song in a music room at the home of Jane Asher, where he was living at the time.
He hoped that it would be released as a single, but it "didn't have quite what was required", and was released on "Beatles for Sale" instead.
"Every Little Thing" is a rare example of a Lennon/McCartney tune in which one member of the partnership was primary composer (here McCartney) but the other sang lead vocal (here John Lennon).
McCartney sings harmony, although one can hear him better in the refrain.
The song's composer is not in question: McCartney claimed the song as described above, and Lennon said in an interview with "Playboy" that McCartney wrote it.
