I've got to admit, I don't watch James Corden, but he has these bits with noteworthy singers where they drive around (not really drive) and sing popular songs while being interviewed. Most of these segments last 8-10 minutes, but recently he did one with Paul McCartney which is really, really good. The bit lasted well over 20 minutes and was very memorable for those who grew up with the Beatles or who are just fans. Take a look, you won't be disappointed.
