I had seen bits of 'Carpool Karaoke' and thought it was probably the stupidest music show ever, showcasing artists I don't give a rat's ass about, but I couldn't help checking it out when I saw that Paul McCartney did a show. If you can keep a dry eye after watching (clips of) Paul doing a surprise set in a Liverpool pub he played 50 years ago, you're a better man than I.
