Paul McCartney’s incredible career began more than 60 years ago when he formed The Beatles with John Lennon, George Harrison, and Ringo Starr. Now, he’s out with his latest solo album "The Boys of Dungeon Lane". In this week's Sitdown, Willie Geist gets together with McCartney to talk about his new music, that includes a song with The Beatles members. And McCartney talks about performing in Stephen Colbert's final "The Late Show" which happened to be on the same stage the Beatles had their American debut in 1964.
