The End of a Chapter, But Not the Music As Stephen Colbert's "Late Show" came to a close, Paul McCartney was the final guest, both as a musician and in a symbolic sense.
The former Beatle brought his signature charm and wit to the show, serving as a reminder of the seismic shift he helped bring about when the Beatles appeared on "The Ed Sullivan Show" 59 years ago.
That historic performance is often credited with launching Beatlemania in America, drawing an estimated 73 million viewers.
