PAUL: " I'M AT IT. BEAVERING AWAY DOING WHAT I LOVE TO DO.AS RINGO SAYS, 'IT'S WHAT WE DO´"

Paul is working with Adele's producer Greg Kurstin on his new album, is currently halfway through his first record since 2013's 'New' and while he is thrilled to be working with Kurstin - who worked on Adele's '25' and Beck's 'Morning Phase' - he's worried that will people will think he's chosen Greg because he is the "flavour of the month".

Paul said: "I'm making a new album which is great fun. I'm in the middle of that. I'm working with a producer I first worked with two years ago on a piece of music I'm doing for an animated film. Since then, he went on to work with Beck and got Best Album of the Year with Beck. Then he went on to work with Adele and has just got Song of the Year, Record of the Year, with Adele, of course and just got Producer of the Year. So my only worry is, people are going to go, 'Oh there's Paul going with the flavour of the month'. But he's a great guy called Greg Kurstin and he's very musical and he's great to work with. So I'm in the middle of that . So yeah, I'm at it. Beavering away doing what I love to do. As Ringo says,'It's what we do.'"

Though the 'Let It Be' hitmaker didn't divulge whether there are any collaborations on the new album, McCartney said that despite duetting with Kanye West, Rihanna, Michael Jackson and many more, none of them will be better than his late bandmate John Lennon.

He said: "My thing with collaboration, I know I can never have a better collaborator than John. That is just a fact. It's inescapable. So I don't try and escape it. I just know there's no way I can find someone now who's going to write better stuff with me than I wrote with John. But having said that, I'm interested in working with other people because they bring their own particular thing to it and, it's interesting. It's educational for me to see how they want to work."
