1) “One Night Only: The Best of Broadway,” 8-10 p.m., NBC. For Broadway, this is the lost year. Shows have been closed since March; they won’t re-open until at least June. Two key openings have been pushed back to September and December. Now Tina Fey hosts a concert from the streets of New York. That includes her “Mean Girls” cast (shown here onstage) and the casts of “Ain’t Too Proud,” “Rent,” “Jersey Boys,” “Jagged Little Pill” and “Diana,” plus Kelly Clarkson, Brett Eldredge and Patti LaBelle.
2) “Silent Night – A Song For the World,” 8-10 p.m., CW. On Christmas Eve, 202 years ago, a small Austrian church’s organ had been damaged by a flood. With only his guitar, the young priest introduced “Stille Nacht,” which he’d co-written. Now that song has been done in 140 languages; Bing Crosby’s 1935 “Silent Night” is the fourth-best-selling single ever. This documentary is flawed, but has gorgeous renditions by Joss Stone, Kelly Clarkson, Shelea Frazier, Katharine McPhee, Lina Markhoul and more.
3) “B Positive” and “Mom,” 8:30 and 9 p.m., CBS. The bad news: After showing just four seeks of new episodes, these comedies have reruns; in fact, it’s the third “B Positive” to rerun, And the good: These are terrific episodes, worth seeing again. First, Drew is adjusting to having Gina (his future kidney donor) as a roommate; she brings big quirks and a big dog. Then is a “Mom” from last season, which means we get Christy, plus hilarious moments with Trevor (Rainn Wilson), Bonnie’s therapist.
4) “Star Trek: Discovery,” 10 p.m., CBS. A series that started with Burnham (Sonequa Martin-Green) disobeying a direct order now finds her captain considering doing the same. The order is to retreat, leaving a planet to be destroyed by the Klingons. This becomes a strong and pivotal episode for the science officer (Anthony Rapp) and the crew, with a sharp jolt at the end of the hour.
5) Movies. It’s Dolly Parton night on CMT. She has small roles in “Coat of Many Colors” (2015) and “Christmas of Many Colors” (2016), at 8 and 10 p.m., based on her songs and life; then she stars in “Unlikely Angel” (1998) at midnight. Alternatives? At 6:15 p.m. ET, Turner Classic Movies has “His Girl Friday” (1940), a smart “Front Page” remake, with the ace reporter (Rosalind Russell) as the ex-wife of the editor (Cary Grant). At 8, TNT has Steven Spielberg’s terrific “Ready Player One” (2018).
