Foo-Fighters_Sheila-E.If the novelty of pop stars singing in their bedrooms is wearing off, here’s a music special taped back far enough that there could be several musicians on stage at the same time to perform before a packed, cheering crowd. Remember what that was like? Way back in January?

“Let’s Go Crazy: The Grammy Salute to Prince” (CBS, 9 p.m.) will at least benefit from great music, as performed by Beck, Common, Alicia Keys, John Legend, Mavis Staples, St. Vincent, Foo Fighters, Usher, Juanes, H.E.R., Gary Clark Jr., H.E.R., Earth, Wind & Fire, Miguel, Susanna Hoffs, The Revolution, Shiela E. and Morris Day and the Time. Maya Rudolph hosts the event, held tonight to mark the fourth anniversary of Prince’s death at 57.

The coronavirus cuts into finale plans for “Empire” (Fox, 9 p.m.), whose send off was supposed to happen two episodes from now. But production was halted in the penultimate episode and we’re left with the third ’til the last now serving as the end of the tumultuous six season run. Directors will try to splice in some of the scenes they got done from the next episode. But barring a full sense of completion there is also talk of a later special movie or something to wrap things up in the future, when things get back to normal some year.

Let’s hear it for the planet: The best of “Seven Worlds, One Planet” (BBC America, 8 p.m.) is fit into one episode. It’s part of an Earth Week run of past nature hits, including a marathon of “Blue Planet II” (BBC America, 3 p.m.).

Catelynn on “Teen Mom” (MTV, 8 p.m.) is old enough now to be two teens.
