CARRIE UNDERWOODBrett Eldredge and Thomas Rhett host “CMA Music Festival: Country’s Night to Rock” (ABC, 8 p.m.),  whose title denotes how the genres have melted, with performances from Aerosmith’s Steven Tyler as well as Luke Bryan, Carrie Underwood, Miranda Lambert, Florida Georgia Line, Blake Shelton, Jason Aldean, Rascal Flatts, Kelsey ballerina, Steven Little Big Town and Keith Urban all perform. The performances came in the June festival in Nashville.

Look who’s talking too: “Koko: The Gorilla Who Talks” (PBS, 8 p.m., check local listings) checks in on the primate, now 45 who was learned to communicate through sign language.

More timely may be “Spillover – Zika, Ebola & Beyond” (PBS, 10 p.m., check local listings) about the spread of diseases from animals (and mosquitos) to humans.

Speaking of bugs, the new kids’ show “Beat Bugs” (Netflix, streaming) licenses all the Beatles songs, has them sung by contemporary artists and puts them to the action of shiny characters traversing adventures and learning lessons. I think I prefer the old “The Beatles Cartoon Show” because it used the band’s original tracks.

Two consecutive episodes of “The Night Shift” (NBC, 9 p.m.) really make it seem like a second shift job.

Jasmine hosts Briana’s baby shower on “Little Women: L.A.” (Lifetime, 9 p.m.).

“Shahs of Sunset” (Bravo, 10 p.m.) conclude their reunion episodes.

The thing that surprises me about “Penn & Teller: Fool Us” (The CW, 8 p.m.) is the sheer number of magicians in the world.

The series “Botched” is usually about repairing bad plastic surgery; the new “Botched by Nature” (E!, 9 p.m.) treats naturally occurring physical aberrations.

“Ghost Hunters” (Syfy, 9 p.m.) return for its umpteenth season. Also back is the similar ghost busting “Paranormal Witness” (Syfy, 10 p.m.).

Finales are reached on the comedies “Young & Hungry” (Freeform, 8 p.m.) and “Baby Daddy” (Freeform, 8:30 p.m.) as well as the boxing saga “Kingdom” (Audience/DirecTV, 9 p.m.).

Darlene and Angela’s plan backfires on “Mr. Robot” (USA, 10 p.m.).

The shooting has fallout on “Greenleaf” (OWN, 10 p.m.).

Mike is still trying to adjust to living in prison on “Suits” (USA, 9 p.m.).

Two days before the opening ceremony, some events begin, in women’s soccer, with USA at New Zealand (NBC Sports, 11:30 a.m.) with a lot of other games, Sweden vs. South Africa, Canada vs. Australia and France vs. Colombia; as well as Brazil vs. China (NBC Universe, 3 p.m.) opposite Zimbabwe vs. Germany (USA, 3 p.m.).
