Chris Rock kicks off the 46th season of “Saturday Night Live” (NBC, 11:30 p.m.), hosting from inside Studio 8H in 30 Rockefeller Plaza for the first time in nearly seven months, in front of a limited audience. Alec Baldwin is back as Donald Trump, though any planned debate skits may have to be adjusted to accommodate the president’s hospitalization. But maybe not.
Jim Carrey dons the aviator shades to play Joe Biden this season, and of course Maya Rudolph returns to revive her her stellar impersonation of Kamala Harris. Megan Thee Stallion is musical guest tonight. The entire cast from season 45 will return, augmented by three new featured players, Andrew Dismukes, Lauren Holt and Punkie Johnson.
The 10 p.m. “SNL” episode is a repeat of last season’s premiere hosted by another who last played Biden on the show, Woody Harrelson; Billie Eilish sings.
What other show can boast a 46th season? How about “Austin City Limits” (PBS, 11 p.m., check local listings), which begins with an overview of performances over the years from John Prine, who died in April of Covid-19.
Earlier, the murder of Emmett Till in 1955 is recounted on “American Experience” (PBS, 8 p.m., check local listings).
