Sir Paul McCartney has revealed that he’s been commissioned to write the music for a ballet.

Details still need to be fleshed out but he’s already started work on the score and says he’s “enthusiastic” about it.

“I’m interested in doing things I haven’t done before,” he said.

“That offer came up and I love writing music, the two went together and I said, ‘Yeah,’ so I just accept things before I even know what I’m doing.”

There’s no set deadline yet and when asked what the ballet would be about, McCartney admitted it was early days.

“I don’t really know that much about it yet,” he admitted. “I’m just writing music for it, but it’s a switch!”
