1) “Queen Family Singalong,” 8 p.m., ABC. Back in 1971, the band Queen formed. With Freddie Mercury as lead singer, it would blast epic anthems, from “We Are The Champions” to “We Will Rock You.” Now its 50th anniversary is being celebrated this week – Monday on “Dancing With the Stars” and again here. Adam Lambert (who often takes the late Mercury’s spot) will perform; he’s shown here. Also performing: Darren Criss, Derek Hough, Fall Out Boy, Pentatonix, JoJo Siva, JimmieAllen and two Broadway casts.
2) Music movies, FX. Here’s another burst of Queen music: “Bohemian Rhapsody” (2018), at 10:30 p.m., has Rami Malek’s Oscar-winning performance as Mercury. It wraps up an FX night stuffed with music. At 6 p.m. is “The Greatest Showman” (2017), a traditional, stop-and-sing musical; as a P.T. Barnum biography, it’s so-so, but the music – sung by Hugh Jackman and others – is potent.At 8 is “Yesterday” (2019), a whimsical gem in which the world suddenly forgets the Beatles.
3) And more music, 9 and 10 p.m., ABC. Next week, the dramas (“Grey’s Anatomy” and such) will be back. For now, here are quick reruns of the second and third episodes of “Queens.” In the opener, four women re-assembled their rap group after 20 years. Now they face personal and onstage crises.
4) “B Positive,” 9:30 p.m., CBS. Last week, this pulled off a rarity – the successful overhaul of a show that didn’t need to change. Gina (the terrific Annaleigh Ashford) bought the nursing home and we met new cast members – including Ben Vereen, Jane Seymour and Hector Elizondo; the opening title song even got a dazzling new production number. Also, Drew finally asked Gina out to dinner. Tonight, he professes his feelings for her; also, she helps a resident whose husband is overprotective.
5) “Tacoma FD,” 10 p.m., TruTV. When the chief needs two-weeks of recovery time, Eddie is in charge … with instant plans to be the “fun chief.” A captain (Nat Faxon) steps in from another shift, instantly taking control of the kitchen. There are some funny moments involving grocery-shopping; the rest of the humor is sort of blunt and obvious.
