TELEVISION - April 9, 1991

He’ll be Home Alone: “Saturday Night Live” is past Macaulay Culkin’s bedtime. The young star of “Home Alone” was set to host the NBC show on Saturday at 11:30, but even his star status couldn’t help him change his curfew. Instead, Culkin’s screen mom, actress Catherine O’Hara, known for TV’s “SCTV” and her role in the movie “Beetlejuice,” will fill the host spot. The band R.E.M. will join her, performing work from their new album, “Out of Time.” The B-52’s Kate Pierson also will make an appearance on the show.
