As the only two surviving members of the greatest band of all time, it's heartening whenever Paul McCartney and Ringo Starr are spotted together, even if it's only having dinner or at some awards show.

So when the drum and bass-playing pair get together for music-related reasons, it's even more special.

Starr had revealed that his former bandmate was one of an array of guests on his new album earlier year, and now the result of one of their collaborations (Macca also plays on another track) can be heard.

It's called 'We're on the Road Again' and is taken from Starr's album 'Give More Love', out in September.
