Sir Paul McCartney's next single will be the theme to a new videogame.

The former Beatles star has collaborated on the score for Destiny, a forthcoming shooter video game for the Playstation and Xbox systems.

His untitled theme was recorded with a 120-piece ensemble at London's Abbey Road studios and directed by Beatles producer George Martin's son Giles.

Destiny will hit stores on 9 September (14) and MCCartney's theme will be released days later, according to reports.
