1) Grammy awards, 8 p.m., CBS. After a nine-week delay, the show booms ahead with Trevor Noah hosting. Performers include H.E.R. (shown here), Billie Eilish, BTS, Olivia Rodrigo, Jon Batiste, Lil Nas X, Brandi Carlile, John Legend and J Balvin, plus country’s Carrie Underwood, Chris Stapleton and Brothers Osborne. A Stephen Sondheim segment has Cynthia Erivo, Ben Platt, Rachel Zegler and Leslie Odom Jr.; there are also gospel, bluegrass and Latin-tropical moments.
2) “Killing Eve,” 8 p.m., BBC America. Villanelle starts the hour with one major problem (an arrow in her back) and ends with another, a fierce fight in a Scottish woods. In between, she seeks members of The Twelve … as do Carolyn (one of the Twelve’s founders) and Eve. It’s a potent and sometimes brutal hour, leading to next week’s two-hour series finale.
3) “American Idol,” 8-10 p.m., ABC. It’s time for the “Hollywood Week” people to do duets. Young singers, some with little experience, are competing with the Grammy superstars, to get our attention.
4) “Billions,” 9 p.m., Showtime, rerunning at midnight. With Axe no longer available to kick around, Chuck (Paul Giamatti) throws his full-force push against Mike Prince (Corey Stoll), putting Prince’s financial world in jeopardy. That sets up next week’s season-finale.
5) “Sanditon,” 9 p.m., PBS. After a tough start, Charlotte manages to find some common ground with her employer – a grim widower who hired her as nanny to his daughter and niece. Also, she and her bright-eyed sister continue to be courted by army officers. It’s a good episode, following a “Call the Midwife” hour that sees a festive anniversary clouded (as usual) by medical tragedy.
