Paul McCartney has said that he still finds it hard to believe that he was in The Beatles.

In an interview with the Metro, McCartney – who releases his new studio album ‘Kisses On The Bottom’ today (February 6) – said that he was pleased the novelty of being in the Fab Four still hadn’t faded for him.

“I’m lucky that I’ve always retained a sense of wonder,” he said. “I was looking at the George Harrison book accompanying Martin Scorsese’s Living In The Material World recently and opened it at a picture George had taken of me and the other guys on an aeroplane.”

He went on to add: “I took me right back; I was like: ‘Was I really there, in The Beatles? Bloody hell!’ It’s obviously a stupid thought but I’m glad I haven’t got used to it yet.”

‘Kisses On The Bottom’ is made up of songs McCartney listened to as a child as well as two new songs, ‘My Valentine’ and ‘Only Our Hearts’. It was recorded with producer Tommy LiPuma, Diana Krall and her band and also features appearances from Eric Clapton and Stevie Wonder.

Earlier this month, McCartney revealed that his love of mischief led him to call the album ‘Kisses On The Bottom’ and that he believed a little controversy is “good for the soul”.

He said: “I like mischief. It’s good for the soul, it’s always a good idea – if only because people think it’s a bad idea.”
