WORTH NOTING ON TV

* WEDNESDAY

NBA final (NBC, 9-11:30 p.m., EDT): The Orlando Magic play the Houston Rockets at the Houston Summit in Game 4 of the best-of-seven pro basketball championship.

* FRIDAY

Michael Feinstein: Sing a Song of Hollywood (American Movie Classics, 8-8:30 p.m.): If anyone needs a reminder of how brilliant and delightful songwriters like Kern, Berlin, and the Gershwin brothers were, Michael Feinstein is the one to do the reminding. He sings their numbers in concerts, nightclubs, and on albums; he talks about them on lecture tours. Accompanying himself at the piano, he approaches the works with an evocative clarity and directness that escapes the annoying mannerism of many latter-day interpreters.

In this two-part program - airing on consecutive Fridays - Feinstein not only performs some film works of the songwriters, but also offers clips from the movies and talks with guest stars.

It's all done, appropriately, in an art-deco club setting redolent of the 1930s. In the opening show, Feinstein's guest is Liza Minnelli; the following Friday it's Gogi Grant.

Firing Line debate (PBS, 9-11 p.m.): They don't mess around; you have to hand them that. On the touchy issue of immigration, the producers have come up with an in-your-face resolution: "Immigration Should Be Drastically Reduced." Captain of the supporting team is host and "Firing Line" founder William F. Buckley, supported by author Peter Brimelow, author-broadcaster Arianna Huffington, and Daniel Stern, head of the Federation for American Immigration Reform.

The opposition is headed by former congressman and New York City mayor Ed Koch. He's backed by Bard College president Leon Botstein; American Civil Liberties Union head Ira Glasser; and Frank Sherry, head of the National Immigration Forum.

Incidentally, three of the debaters - representing both sides - are immigrants themselves.
