McCartney said he was gripped by depression and "took to the bevvies" and almost walked away from his music career entirely when the iconic four-piece band, which also included John Lennon, George Harrison, and Ringo Starr, went their separate ways in 1970, reported Female First.
"I was depressed at the time, yeah. You would be. You would be too. I was breaking from my lifelong friends, not knowing whether I was going to continue in music. I took to the bevvies. I took to a wee dram," McCartney said.
