“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.
