James Corden is always upbeat, positive, and most of all, funny. But on a recent show with Beatles star, Paul McCartney, he showed off a different side. Corden couldn’t help but break down to tears when Paul McCartney revealed the inspiration behind the hit song, “Let It Be.”

The two stars rode around Liverpool checking out McCartney’s old hangout spots and talking about his time with the Beatles. When “Let It Be” started playing in the car, McCartney took the time to tell the story of how he came up with the name and the lyrics.

His mother came to him in a dream and reassured him that everything was going to be okay, that life was going to be fine, and told him to just let it be.

Paul remembered her words vividly, and it inspired him to write one of the greatest Beatles hits of all time. Corden told McCartney that it was the most beautiful story he had ever heard, and you can see Corden’s eyes welling with tears as they took a small moment of silence.

Corden explained that he had gotten so emotional because his most pivotal memory of his deceased grandfather included the Beatles hit, “Let It Be.” His grandfather was also a musician, and he sat him down one day to have a discussion with him about inspiration. He told Corden that he was going to play him the best song he had ever heard, which was “Let It Be.”

The mood did eventually change to a happier tone, and the two started performing duets of songs such as “Penny Lane,” “Drive My Car” and many others. The duo surprised fans at one of McCartney’s favorite pubs with an impromptu concert, performing hits such as “Hey, Jude.” It’s an afternoon everyone will remember and cherish forever.
