Paul McCartney's 'Carpool Karaoke' takes a sad song and makes it better

Imagine singing an emotional duet to "Let It Be" in the car with the man who wrote it.

That little bucket list item was ticked by James Corden, who dropped the full instalment of "Carpool Karaoke" featuring legendary Beatle Paul McCartney on Thursday night's The Late Late Show.

A jolly good sport who genuinely looks like he had the best time, McCartney runs through some of his most iconic numbers, from the thematically necessary "Drive My Car," to "Penny Lane," and the first song he ever wrote at 14. Oh, and a little song called "Let It Be."

Corden takes McCartney on a little trip down memory lane around Liverpool in the episode, including a visit to the legend's former childhood home, and of course, Penny Lane, and it all ends in a local pub with the pair singing "Hey Jude," to some surprised locals. 

What a legend.
