Late-night television closed a major chapter as Stephen Colbert signed off from The Late Show with an unusually intimate farewell, capped by Paul McCartney returning to the Ed Sullivan Theater to sing “Hello, Goodbye” and helping drive the finale to a striking 6.74 million viewers, the show’s biggest weeknight audience ever. Elsewhere, entertainment news carried a darker note with newly released 911 audio describing NASCAR star Kyle Busch coughing up blood and struggling to breathe shortly before his death, as investigators continue to examine the circumstances. Onstage drama unfolded in Montenegro, where Ricky Martin briefly halted a concert after tear gas was discharged toward the stage, though he later returned and finished the show. And at the box office, Star Wars’ theatrical comeback looked muted: The Mandalorian and Grogu opened to about $12 million in Thursday previews, a softer-than-hoped start for a franchise absent from cinemas for seven years.
