James Corden did a carpool karaoke with Paul McCartney through Liverpool. With 23 minutes it was one (maybe even) the longest carpool session and I usually don't watch such long YouTube videos, but every minute was worth it.
It's really worth watching. It was a tour of Liverpool itself, but also around Paul's child house, plus they visited the street Penny Lane, where Paul singed a painted street sign (haptic street signs of that street don't exist). At the end Paul and James played a suspire gig at a pub.
The carpool session was so emotional that James started to cry and there was a breathless, eerie silence in the car for a moment.
