If it’s a new year, it’s time for Dick Clark

Yo, 2003! You’re getting a royal welcome tonight when ABC presents “Dick Clark’s New Year’s Rockin’ Eve,” beginning at 10 p.m. Clark, who has done more rockin’ in Times Square (this is his 31st straight year in New York) than he did in Philadelphia on “American Bandstand,” starts his three-part special with highlights from musical tours across America in 2002 that feature Alabama, Coldplay, LL Cool J and the Who. Between songs, Steve Doocy and Mario Lopez will report on happenings around New York City.

At 11:30, the countdown to midnight begins, and it will include reports from Ali Landry (“Spy TV”) at a party in Hollywood. Landry will be joined by B2K, Rod Stewart, Nelly and Missy Elliott.

After midnight, the music and revelry continue until Clark closes it out in the wee hours.

Ryan Seacrest (“American Idol”) celebrates as the host of “America’s Party: Live From Las Vegas,” at 11 p.m. on Fox. The bash gets going with performances by the Rolling Stones, Bon Jovi, Sheryl Crow, Sugar Ray and Ja Rule.

The Ebony Ecumenical Ensemble and soloists will perform music from “Porgy and Bess” and “An American in Paris.”
