1) “All in the Family” and “The Jeffersons,” 8-9:32 p.m., ABC. Jimmy Kimmel was 4 when TV comedy was transformed by “All in the Family”; other Norman Lear shows followed, including “The Jeffersons.” This season, Kimmel had a live special, using two old scripts and new actors — Woody Harrelson and Marisa Tomei as the Bunkers (shown here), Jamie Foxx and Wanda Sykes as the Jeffersons. It drew10 million viewers, reran … and now re-reruns, with a “20/20” follow-up at 9:32 and Kimmel at 10.
2) “Woodstock at 50,” 9 p.m. ET, CNN (barring breaking news). Fifty years ago, the Woodstock music festival was in its final night. Now Bill Weir talks to some of the performers (David Crosby, Graham Nash and John Fogerty), organizers and people in the crowd. He looks at the modern music-festival industry and at the values offered by the original event.
3) “Gates of Paradise,” 8-10 p.m., Lifetime. For the past three Saturdays, we’ve seen Annalise Basso, 20, as Heaven Casteel. Now the saga (from V.C. Andrews novels) jumps forward, with the focus on Lizzie Boys as Heaven’s daughter, Annie. After a tragedy, she’s whisked to the family mansion and her grandfather (Jason Priestley). You can catch the previous films at 2, 4 and 6 p.m.; the final one – a prequel, revealing family secrets – will be next Saturday.
4) “So You Think You Can Dance” (Fox) or “NCIS: Los Angeles” (CBS), 8 p.m. Pick a rerun here. In one, the top 10 guys each dance with an all-star partner. In the other, a Navy officer collapses on the job; the team must determine if it’s a terror threat or stress-induced.
5) “Saturday Night Live,” 11:29 p.m., NBC. Jonah Hill hosts, with Maggie Rogers, 25, making an impact as the music guest. After Pharrell Williams discovered her during a New York University master class, a video went viral and Capitol Records signed her. Rogers’ album debuted at No. 2 on the Billboard chart in January, two months after this “SNL” aired.
