1) CMT Music Awards, 8 p.m., CBS. Country music fills the night, including the Judds’ (shown here) first TV performance in 20 years. Other duos include Maren Morris with Ryan Hurd, Cole Swindell with Lainey Wilson, Mickey Guyton with Black Pumas, Jason Aldean with Bryan Adams, Thomas Rhett with Riley Green and Jimmie Allen with Monica and Little Big Town. Also performing: Carrie Underwood, Keith Urban, Kelsea Ballerini (who hosts with Anthony Mackie), Kane Brown, Miranda Lambert, Walker Hayes, Carly Pearce, Old Dominion.
2) “9-1-1,” 8 p.m., Fox. Maddie and “Chimney” (Jennifer Love Hewitt and Kenneth Choi) are finally back with their colleagues – but not together. They were lovers and have a baby, but Maddie had severe postpartum depression. Now (after Hewitt’s real-life maternity leave) they have issues to sort out. That comes in a strong hour that also has three major emergencies, complete with spiders, a sharks and a dousing of gasoline.
3) “9-1-1: Lone Star,” 9 p.m., Fox. After that strong “9-1-1,” its spin-off has a sub-par hour. It starts OK, with perhaps the only time you’ll hear someone say “look for a biker in a haystack”; then it tries some personal stories. One, involving Owen (Rob Lowe) is silly, but not in a good way. The other involves his son TK, in tangles that involve his boyfriend and his Alcoholics Anonymous sponsor. It’s earnest, but plodding.
4) “American Idol,” 8-10 p.m., ABC. Here’s the second half of the Hawaiian-resort phase for the show’s 24 contestants. Bebe Rexha is tonight’s mentor; viewers will vote, deciding who’s in the top 20 on Sunday.
5) ALSO: If you missed the excellent “Killing Eve” series-finale on Sunday, catch a quick rerun from 9-11 p.m. on AMC. And “Harry Wild” has two more episodes, at www.acorn.tv. The first (like last week’s openers) is slick and fun, as Harry (Jane Seymour) gets her granddaughter to go undercover. The second, alas, wades into the cliché of a killer planting clues, daring to be caught. If only they would do that in real life
