When Conan O’Brien returns to late night in November, it won’t be with longtime bandleader Max Weinberg.

O’Brien announced Monday that he and Weinberg had parted ways after 17 years.

Jimmy Vivino, who had frequently filled in for Weinberg on “Late Night” and “Tonight,” has been tapped to replace Weinberg as the new band director on the upcoming TBS yakker “Conan.”

Vivino has often subbed for Weinberg as band leader, as Weinberg — a member of the E Street Band — occasionally took leaves of absence to tour with Bruce Springsteen.

“Conan” has not yet announced the new name of O’Brien’s house band — previously known as “The Tonight Show Band” during O’Brien’s stint on that show, and before that as the “Max Weinberg 7.”

News was not a surprise — Weinberg continues to tour the country with his new big band, and had already announced tour dates that would have conflicted with the “Conan” launch.
