A new song by Paul McCartney -- slated for the upcoming soundtrack of the Robert De Niro movie 'Everybody's Fine' -- has leaked online. Titled '(I Want To) Come Home,' the track has been made available via YouTube.

The film is about a widower named Frank, played by DeNiro, who sets up a road trip to reunite with his grown up children. "I could definitely identify with Robert De Niro's character because I have grown-up kids who have their own families," McCartney said in a statement. Macca says he was given an early screening of the movie, went home and wrote the song that evening.

The film, which stars Kate Beckinsale, Drew Barrymore and Sam Rockwell as DeNiro's children, hits theaters in December just as McCartney launches his "Good Evening Europe" jaunt. Sir Paul, 67, will kick off his tour in Hamburg, Germany, where the Beatles honed their craft in the early '60s, on Dec. 2nd. He also has dates set for Berlin, the Dutch city of Arnhem, Paris, Cologne and Dublin before wrapping the trek on Dec. 22 at London 's O2 Arena.
