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

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'."
