1) “Carpool Karaoke,” 10 p.m., CBS. You never know what kind of musician you’ll get at an English pub, but this exceeded all expectations: It was Sir Paul McCartney. That was one of the highlights, as James Corden – an English kid, born eight years after the Beatles broke up – joined him. They visited a Beatles statue (show here), McCartney’s childhood home and some places mentioned in “Penny Lane.” The result is nominated for five Emmys, including best variety special not done live.
2) “I Ship It” debut, 9:30 p.m., CW. Here’s something fresh and fun, for the final weeks of summer. A reworking of a 2016 digital series on CW Seed , it has a young woman with big dreams (writing fan fiction about her favorite show) and a small job, at a shipping office. This is smartly spiced by scenes from her fiction – with Ethan Peck, Gregory’s grandson, as the handsome hero – and three songs. All are clever … and one is beautifully illustrated via (really) a copy machine.
3) “The Terror: Infamy,” 9 p.m., AMC, rerunning at 11:08. If this were simply a story of the Japanese-American internment, it would be filled with horrors. Tonight, families are herded to horse stables in North Dakota and then to Oregon. But on top of that, Chester and others keep seeing Yuko, an evil (albeit beautiful) spirit. Like last week’s opener, this is visually gorgeous, beautifully directed by Josef Kubota Wladyko. It’s also deeply disturbing.
4) “The Big Bang Theory,” 8:30 and 9 p.m., CBS. The first rerun is hilarious, with people trying to get into a Dungeons & Dragons game that includes William Shatner and Kareem Abdul-Jabbar. The second is fairly good, with friends trying some psychological testing on the Wolowitz kids.
5) ALSO: On “So You Think You Can Dance” (9 p.m., Fox), the field is trimmed from 10 to eight. On “Grand Hotel” (10:01 p.m., ABC), Danny is finally working with police, to learn what happened to his sister. And “My Life is Murder” (any time, www.acorn.tv) again has a sleek hour that’s entertaining, despite a so-so mystery. Alex (Lucy Lawless) ponders a businessman’s bike-ride death.
