Sir Paul McCartney cannot stop getting killed when he plays video games with his grandchildren.

The 72-year-old musical legend has written a new track, 'Hope for the Future', for the video game 'Destiny' but admits that he's not great at succeeding in the game.

Speaking on 'The Daily Show with Jon Stewart', he said: ''I'd seen my grandkids playing them and I'd say 'Give me a go on that, come on' and I would get killed within the first couple of seconds.

''I've tried them but I'm no good at them. I go in the first room and I'm like 'yes, come on!' and people are just shooting at me. They're shooting at me! I get killed and hand the controller back.''

Meanwhile, the former Beatles star recently revealed he was ''intrigued'' by the prospect of writing a song for a video game.

He explained: ''They approached me though my manager. I spoke to the game studio's composer, Marty O'Donnell, and he asked if I fancied contributing to the soundtrack of a new video game.

''I didn't know anything about it, but he showed me some concept art, and I got intrigued. He said they'd like a song, and perhaps some collaboration on the score. I ended up sending him some musical phrases that I thought would be appropriate for the epic nature of the game.''

He added: ''I was thinking of it as a blockbuster movie. The nearest I'd ever done was 'Live and Let Die', which was a little bit unusual, but I enjoyed the experience. This was just as intriguing.

''I liked the idea that there would be a whole bunch of people who would hear my music who wouldn't normally hear it. I just thought, 'Oh, I'll give it a go'.''
