James Corden and Paul Mc Cartney on 'Carpool Karaoke'

Watch Paul McCartney's super fun Carpool Karaoke full of hits

James Corden's most recent "Carpool Karaoke" guest was Sir Paul McCartney, who managed to reduce him to tears at one point during the sketch.

After singing "Drive My Car" and the first song he ever wrote, a ditty called "I Lost My Little Girl", Paul explained how the genesis of "Let It Be" came to him in a dream. McCartney expresses surprise that songs like "Blackbird" and "Let It Be", both performed during the in-car scenes, have stood the test of time.

The segment climaxed with Paul returning to one of the pubs Paul used to play before The Beatles hit the big-time, surprising the locals with a performance with his current band - singing hits decided by the audience via a jukebox. "Can you please, please help me" before joining Paul in a rendition of Drive My Car.

Corden responded, "That's the most attractive story I've ever heard", and then the two sang the song together. They also stopped by the barber shop mentioned in "Penny Lane" and mingled with excited fans along the sidewalks. The Beatles leader might have a stronger connection with Corden than any other late night host because they're both British, and Corden was moved so much by something McCartney said that he was overcome with emotion. "She said, 'Let it be.' I've never heard that, that's kind of good.' So I wrote the song 'Let It Be, ' but it was her positivity".

"I've never been in since I lived there", Sir Paul says. "I can remember my granddad, who's a musician, and my dad sitting me down and saying, 'We're going to play you the best song you've ever heard, '" he said.

The segment started with Corden seated in his vehicle before making a phone call and channelling one of The Beatles' best-known hits.
