Colbert appeared tried to play into the rumor with a gag where he was ready to introduce the Pope before a staffer came out on stage an said Leo was refusing to come out because “We didn't read his whole rider, and we didn't get him his snacks.” Colbert then said: “The pope, who was definitely my guest tonight, has canceled. We already sent the other stars away. This is terrible.” The comedian then welcomed music legend and Beatles member Paul McCartney as his last guest. McCartney reminisced about coming to the Ed Sullivan theater and said “We came here, and you had to go a few floors down to get makeup. We went down there, and the girls put makeup on us, and it was, like, bright orange.” Colbert, who handed cracked a Trump joke in his monologue then quickly took a shot at the president and quipped: “That’s very popular in certain circles these days.”Paul McCartney leaves the "The Late Show" following the taping of the final episode.Getty ImagesWhat Did Colbert Say About Cbs?Although he interrupted his audience from booing mentions of this being his last show during the opening, the comedian managed to land a jab at his network later. In his recurring segment called “Meanwhile,” the comedian talks about the owner of music used in the “Peanuts” animated specials suing several people, including the U.S. government, for using the songs without permission. Now, 'Peanuts' is a powerful brand and corporation in and of itself. Anyone illegally using that music is going to have to pay through the nose,” Colbert said before his live band started playing the tunes. Colbert then identified the tunes as music from the ‘Peanuts’ and joked, “Oh no, I hope this doesn’t cost CBS any money.” The network had previously claimed their decision to cancel Colbert was a “purely financial” one and nothing to do with politics or pressure from the Trump administration as some have alleged.What Happened In The Final Segment Of The Late Show Finale?Colbert abruptly ended McCartney’s interview as part of the closing skit where he went backstage to solve a “technical problem.” Colbert met astrophysicist and broadcaster Neil deGrasse Tyson backstage where here mentioned a “interdimensional wormhole” was forming and if it grows “all of late night television could be destroyed.” Colbert pushed Tyson into the wormhole before Jon Stewart appeared to deliver a message on behalf of Paramount, the network’s parent company. Stewart then fired a few jabs at the company, appearing to reference the recent editorial direction of CBS’ news division, and read out a satirical statement. “Paramount strongly believes in covering both sides of any black hole that is swallowing everything we know and love, and the coverage must also include the positive aspects of the insatiable emptiness.”
