The Night that Changed America: A Grammy Salute to the Beatles (Sunday, 8 p.m., CBS)

On Sunday, various performers such as Annie Lennox and Alicia Keys will try to recreate that magic by singing their classic songs. That year, The Beatles won the Best New Artist award at the Grammys, a harbinger of things to come.

Then, heaven forfend, the Dowager Countess (Maggie Smith) falls ill with bronchitis, and is nursed by a selfless Isobel (Penelope Wilton), who cheerfully ignores her patient’s snippy comments. Meanwhile, in the agrarian part of the estate, Mary and Mr. Blake (Julian Ovenden) visit the newly arrived pigs; finding them dehydrated, they carry buckets of water together, getting muddy and really rather enjoying it. Lady Rose (Lily James, right) continues to hit on Jack (Gary Carr, left). An unexpected — and unwanted — visitor arrives, setting everyone on edge.

The Walking Dead (Sunday, 9 p.m., AMC)

With the destruction of the prison in the winter finale, the group of survivors on “The Walking Dead” is broken apart and exposed to new dangers, new enemies and heartbreaking choices. They will have their faith thoroughly tested — a faith that breaks some of them and redeems others. In the first new episode of the remaining season, Rick (Andrew Lincoln) deals with the zombie apocalypse and his son Carl (Chandler Riggs). New members of the cast will be joining the show in the next few weeks, among them Michael Cudlitz of “Southland.” Until then, we can content ourselves with Michonne (Danai Gurira) and Daryl (Norman Reedus).
