Was too drunk to write songs after Beatles split: Paul McCartney

London: Paul McCartney says he battled a drinking problem after the legendary band Beatles broke up.

The 69-year-old musician, who used to hit the bottle at his hideaway on the Mull of Kintyre, says he was so drunk that he was unable to write songs, reported a website.

"I overdid it, basically. I`d drink whisky, of which there was a large supply in Scotland. What happened was The Beatles, towards the end, was very constricting.

"You were in a corporate world suddenly. It`s not what you get into music for, but it`s there. It got very heavy, so me and Linda (wife) escaped with the kids, but the business hassles were still there.

"So I think I was just trying to escape in my own mind. I had the freedom to have just have a drink whenever I fancied it. I`d go into the studio, maybe have another drink and so on. I got to a point where Linda had to say `Look, you should cool it`," he said.
