Stephen Colbert ends CBS’s “The Late Show” with a final episode that blends comedy with a sci-fi-themed sendoff. Multiple outlets report that the finale includes Colbert’s well-known circle of fellow hosts and guest appearances from major music figures. NPR highlights a “powerful musical sendoff” that incorporates sci-fi elements through a large wormhole visual. Performers mentioned include Paul McCartney, Elvis Costello, and Jon Batiste, along with additional guests. The New York Times similarly describes Colbert’s finale as a notable event in the show’s closing moments, stating that famous friends and special guests join him for the conclusion. Both accounts present the wormhole as a central feature of the final segment and frame the episode as a concluding performance with prominent musicians. The coverage focuses on the event’s spectacle and guest lineup, without detailing specific plot beyond the show’s sci-fi sendoff and musical finale.
