As has been noted, Max Weinberg is not resuming his musical duties with Conan O'Brien. Here's the word about his replacement:
Conan O’Brien will have more familiar faces with him on TBS when Conan debuts Monday, Nov. 8, at 11 p.m. (ET/PT). The newly minted band will be led by Jimmy Vivino, former associate music director, arranger, guitarist and vocalist for The Tonight Show with Conan O’Brien and Late Night with Conan O’Brien.
In addition to Vivino, The Basic Cable Band will consist of Scott Healy (keyboards); Mike Merritt (bass); Mark Pender (trumpet); Richie “LaBamba” Rosenberg (trombone); Jerry Vivino (saxophone, woodwinds and vocals); and James Wormworth (drums).
