A couple of football giants are subjects of magazine shows tonight, for vastly different reasons; and Maryland Public Television offers a clever but seldom seen Ginger Rogers movie.
* "Dateline NBC" (8 p.m.-9 p.m., WBAL, Channel 11) -- Bob Costas interviews retired football quarterback Joe Montana, who plans to become a broadcaster. Katie Couric also takes a look at the making of "Pocahontas," the latest Disney money-making machine. NBC.
* "NBA Basketball Finals" (9 p.m.-11:30 p.m., WBAL, Channel 11) -- The Houston Rockets come-from-behind win Wednesday gave them a 1-0 lead in the championship. The Orlando Magic play catch-up tonight in their home Orlando Arena. NBC.
* "Great Performances: 'Sondheim: A Celebration at Carnegie Hall' " (10 p.m.-11:30 p.m., MPT, Channels 22, 67) -- From "Sweeney Todd" to "Into the Woods" on the stage, and even "Dick Tracy" at the movies, the composer has scored some memorable melodic productions. Patti Lupone, Cleo Laine, Bernadette Peters, Liza Minnelli and Betty Buckley are among the performers singing from the Sondheim repertoire in this repeat. PBS.
* "20/20" (10 p.m.-11 p.m., WMAR, Channel 2) -- Barbara Walters checks in on the O. J. Simpson story with an interview with Fred and Kim Goldman, the father and sister of Ronald Goldman, who was slain last summer with Nicole Brown Simpson. Who do they think did it?

* "The Major and the Minor" (11:30 p.m.-12:40 a.m., MPT, Channels 22, 67) -- Ginger Rogers, who died in April at the age of 83, had a talent for playing childish roles. Most film buffs remember her taking that youth potion in "Monkey Business" (1952, with Cary Grant). Here's an additional film with a &r; somewhat similar role, an early hit (1942) of director Billy Wilder. To save train fare, Rogers' character pretends to be a 12-year-old girl, and is befriended by an Army officer headed home to get married (Ray Milland). She must follow through on the masquerade when he's confronted with reports that he shared a sleeping compartment with another woman. Ironically, in this more innocent time no one has a problem with a man befriending a young girl.
* "Investigative Reports" (9 p.m.-10 p.m., A&E; Network) -- The recent nerve gas attack in the Tokyo subway provides a timely backdrop to a report on new technologies of germ warfare. Host Bill Kurtis examines international efforts to reach new accords on curbing the use of such weapons.
