“Weird Al” Yankovic presents his first televised comedy special since 1999. “‘Weird Al’ Yankovic Live! — The Alpocalypse Tour” (8 p.m., Comedy Central) offers material old and new from the king of music and music video parody.

Actually, “king” is a slight misnomer, implying that Yankovic actually has song parody subjects. He pretty much has the pop put-on market all to himself. That’s been good for Weird Al, but a bit of a shame for the rest of us. There was a time when the radio airwaves were filled with novelty songs, mostly one-hit wonders by unknown artists. But since MTV, the music business has grown ever more corporatized and homogenized. It seems there’s room only for Weird Al.

• On another musical note, “Celine: 3 Boys and a New Show” (8 p.m., OWN) offers a glimpse at Celine Dion, the Quebec-born singer, as she takes care of her family and prepares for a new Las Vegas show.

• Screen veterans Cheryl Ladd and Bruce Boxleitner appear in “Love’s Everlasting Courage” (8 p.m., Hallmark), the latest prequel to the series of movies based on the “Loves Comes Softly” books by Janette Oke.
