1) “United We Sing,” 8-10 p.m., CBS. Harry Connick Jr. and his daughter Georgia (a filmmaker) take a road trip to honor workers. They meet famous friends (Oprah Winfrey, Brad Pitt, Queen Latifah, Drew Brees) and hear music from the greats of jazz (Herbie Hancock, Jon Batiste, Wynton and Branford Marsalis) and more (Tim McGraw, Cyndi Lauper. John Fogerty, Andra Day, Jame Foxx, Little Big Town). Then Connick, Irma Thomas and Trombone Shorty perform in iconic New Orleans locations.
2) “A Bigger Love,” 8-9 p.m., ABC. Two new music specials colliding on a summer night? That’s what TV’s time-shifting devices are for. “Love” is keyed to Father’s Day; John Legend includes his wife (Chrissy Teigen) and their two kids. He does songs from his new album and has guests, musical (Stevie Wonder, Common, Ne-Yo) and beyond (Jim Gaffigan, Shaquille O’Neal, Anthony Anderson, etc.)
3) “Lucy Worsley’s Royal Myths & Secrets” opener, 8 p.m., PBS. The British love the notion of Queen Elizabeth I on horseback, rallying her troops to crush a Spanish invasion. But when she gave the speech, Worsley says, the Spanish armada was already in retreat. This first hour, devoted to debunking Elizabeth, is fairly good. It’s followed by two “Masterpiece” hours – an excellent “Grantchester” at 9 (a hit-and-run mystery) and a so-so “Beecham House” at 10 (John’s verbose mother tries to take over).
4) “The Chi” season-opener (Showtime) and “Perry Mason” debut (HBO), both 9 p.m. The cable giants collide. HBO has a great concept (Mason before he was a can’t-miss lawyer) and two gifted actors (Matthew Rhys of “The Americans” and Tatiana Maslany of “Orphan Black”), but “Chi” has perfect timing: More than ever, we need this deeply human story of black life in Chicago. And at 7 p.m. ET (4 p.m. PT), “The Chi With Love” is on YouTube, featuring Common and other hometown musicians
5) ALSO: Two cable dramas have season-openers, back-to-back. “Yellowstone” (9 p.m., Paramount) finds John (Kevin Costner) stirring up politics and helping his grandson deal with nightmares; also, his daughter finds someone with big plans for the neighboring land. “NOS4A2” flashes ahead eight years, with Vic happy to be a small-town mechanic and mom. Then she learns the evil Charlie Manx is back.
