Sir Paul McCartney still finds releasing new music as stressful as taking a school exam.

The former Beatle unveiled his latest album New on Monday (14Oct13) and still considers the experience nerve-wracking despite his long career.

He says, "You think it's just for you, your friends and your family but when you put it out you realise you're putting it out for people to have opinions on. It's like you've entered yourself for an exam you didn't know you were entering."
