Paul McCartney has revealed that he suffered from depression after The Beatles split up in 1970.

In a new interview on BBC Radio 4 show Mastertapes - which was filmed and which you can watch below - the 73-year-old said that the split hit him hard and that he turned to alcohol for a time.

He said: "It was difficult to know what to do after The Beatles. How do you follow that? I was depressed. You would be. You were breaking from your lifelong friends. So I took to the bevvies."

He also spoke about what ultimately drove The Beatles apart, and unsurprisingly there was no mention of Yoko Ono. Instead, he said that the band's business affairs and "heavy meetings" were "doing my head in".

After The Beatles split, of course, McCartney eventually formed Wings and he credits his late wife Linda as helping him through the difficult period. "I liked the idea of a band. I wanted to go back to square one," he said, adding: "We were terrible. We weren't a good group. People said, 'Linda can't play keyboards', and it was true."
