Paul McCartney has shared the original song he wrote for the video game Destiny.

Recorded with a 120-piece orchestra and conducted by Sir George Martin's son Niles, at the Abbey Road Studios in London, the track is called "Hope For The Future."

It appears in the end credits of the first-person shooter video game. The track forms part of over 50 minutes of music McCartney composed for the game alongside Marty O'Donnell and Mike Salvatori.

"There was no check involved, big or otherwise. He's in it for the creativity. He got a wonderful opportunity to reach an audience that wouldn't typically be immersed in Paul McCartney."

O'Donnell added of the recording process: "He brought out his old tape-loop machine - he said the last time he used it was on Sgt. Pepper.

So he sent me an entire session where he was playing around with all these tape-loops. We were just thrilled. That was the same machine that was on Revolver."

The track will be available as a single, though details of the release have not been revealed.
