Kanye West has earned some very lofty comparisons during his career (including from himself -- "I Am A God," anyone?), and now he can add another to that list: John Lennon.

"When I wrote with John, he would sit down with a guitar," Lennon's Beatles bandmate Paul McCartney told The Sun, as reported by Mirror Online. "I would sit down. We'd ping-pong 'til we had a song. It was like that [with Kanye]."

One of those ping-pong sessions helped lead to Yeezy's "Only One," which features McCartney.

"We sat around and talked an awful lot just to break the ice," he explained. "One of the stories I told him was about how I happened to have written 'Let It Be.'"

"My mom came to me in a dream when she'd died years previously. I was in a bit of a state -- it was the '60s and I was overdoing it. In the dream she said, 'Don't worry it's all going to be fine, just let it be.' And I woke up and thought, 'Whoa,' and wrote the song."

Similarly, Kanye channels his late mother, Donda, in "Only One."

"I told Kanye this and he said, 'I'm going to write a song with my mom.' So then I sat down at the piano."

Everything that we've heard from the two so far -- "Only One," "FourFiveSeconds" and "All Day" -- has made it pretty evident that they found a musical groove and comfort, but the 72-year-old Brit wasn't always sure things would go smoothly.

"My first thought was, 'Whoa, what am I going to get into here?'" he admitted. "He is amazingly talented but controversial and can make eccentric moves. I realized if it didn't work out we'd just say so and shake hands and leave."

Luckily for us, that's now how things worked out.
