Paul McCartney helps Stephen Colbert say goodbye to 'Late Show'

Comedian Stephen Colbert signed off from his late-night talk show on Thursday after 11 seasons with a sentimental chat with Beatles musician Paul McCartney and pointed jokes about his forced departure from CBS. The final installment of "The Late Show with Stephen Colbert" began with the comic thanking the in-person and television audience for watching ​his nightly take on ‌current events, often punctuated by verbal jabs at Republican President Donald Trump.
