VIDEORGY: If you’re having trouble figuring out how to get warmed up for the Grammy telecast, tune in early for “Weird Al’s Guide to the Grammys,” a half-hour special to air Tuesday at 7:30 p.m. on KCBS-TV Channel 2, immediately before the big show. Hosted by Weird Al Yankovic, it’ll feature such Grammy-going advice as how to shop for the right limousine and how to react if you lose as well as mock interviews with pop heavyweights like Prince and Bruce Springsteen. However, our favorite segment, titled “Frankie Goes to Hollywood,” features a pool-side jam session between Weird Al and polka-king Frankie Yankovic (no relation). The duo celebrate the Grammys’ newest category, “Best Polka Recording,” by performing a polka medley of all the entries in the “Song of the Year” category, including even a wheezing accordion duel on “Born in the U.S.A.” . . . Today is “Pleasant Valley Sunday” on MTV, largely because the 24-hour video channel is airing 46 consecutive installments of “The Monkees,” the dizzy ‘60’s schiz-com, which featured the world’s first made-for-television pop band. (The Monkees marathon broadcast was scheduled to begin at 9 p.m. Saturday, with the show’s pilot episode, which--attention trivia buffs--was co-written by film director Paul Mazursky.) If you miss the first batch of episodes, MTV will begin airing the entire series again in March, with two shows airing each day, at 9 a.m. and 5 p.m. . . . And this month’s installment of “The Cutting Edge,” which airs on MTV at 7:30 tonight, features a rare TV interview with Tom Waits; new rehearsal footage of X, with the band’s new “permanent-for-now” lineup; a chat with Jonathan Richman; social advice from Black Flag’s “Dear” Henry Rollins; and new videos from Jesus & Mary Chain, the Waterboys and the Golden Palominos.
