A SPECIAL U.K. edition of “Carpool Karaoke” took an emotional turn as Sir Paul McCartney joined James Corden on a trip to Liverpool.

The “Late Late Show” host was joined by the singer as they drove past famous Beatles landmarks.

McCartney told how a dream in which his mother told him to “let it be” inspired the song of the same name.

Corden said it was the “most beautiful story” he had ever heard, before singing a teary rendition of the song.

“Oh man, it got me emotional there,” Corden said. “I didn’t feel it coming.”

McCartney recalled how he “had a dream in the ‘60s where my mum, who died, came to me in the dream and was reassuring me, saying, ‘it’s going to be OK. Just let it be.’”

Explaining why the story made him so emotional, Corden said: “I can remember my grandad, who was a musician, and my dad, sitting me down and saying, ‘we’re going to play you the best song you’ve ever heard’.”
