Tony Bennett Celebrates 90: The Best Is Yet to Come (9/8c, NBC): Some serious pipes threaten to blow off the roof of the renowned Radio City Music Hall in honor of a truly legendary crooner, still going strong at 90. Bennett’s recent recording/concert partner Lady Gaga leads the musical celebration, joined by Michael Bublé (whose holiday musical special airs an hour earlier) and a staggering lineup including Billy Joel, Elton John, Stevie Wonder, Hamilton’s Leslie Odom Jr., k.d. lang, Diana Krall and classical artist Andrea Bocelli.

Good Behavior (9/8c, TNT): We know a lot about Letty (Michelle Dockery), but not so much about mystery man Javier (Juan Diego Botto)—which might chance when Letty accompanies the hot assassin to a family reunion, posing as his girlfriend while seeking clues about his past.

Year in Review: Many would like to put 2016 in the rear-view mirror and never think about it again, but first, there are the year-end retrospectives. ABC’s The Year: 2016 (9/8c), hosted by Robin Roberts, brings together ABC News’s correspondents and anchors to relive the defining moments of the year—political for sure, but also cultural breakouts like Netflix’s Stranger Things and the Olympic women’s gymnasts. The Olympics are also a topic of a year-end edition of HBO’s Real Sports With Bryant Gumbel (10/9c), which revisits the show’s groundbreaking report on the controversies surrounding the all-powerful International Olympics Committee. A roundtable including Mary Carillo, Jon Frankel, Bernard Goldberg, Andrea Kramer, Soledad O’Brien and David Scott join Gumbel to look back at this distinguished sports newsmagazine’s top stories.
