James Corden isn't the only one who ends up crying as no less than Paul McCartney rides shotgun for Carpool Karaoke

      There are celebrity encounters, and then there are celebrity encounters so far up the bucket list that they move a person to tears.

      James Corden's Car Pool Karaoke series has seen him climb behind the wheel with some mega-heavy hitters. Think Madonna. Lady Gaga. Gwen Stefani. Or driving around the White House grounds with Michelle Obama while Missy Elliot got her freak on in the back seat. 

      This week's Late Late Show With James Corden Carpool Karaoke segment was in an entirely different stratosphere. 

      Imagine not only getting the chance to um, beetle, around Liverpool with a geniune Beatle, but also visit Paul McCartney's childhood home to sing a song in front of the piano.

      Watch above. And then, like James Corden, get ready to cry.
