WORTH NOTING ON TV

* FRIDAY

In Concert (ABC, 12:06-12:36 a.m. - technically Saturday morning): This edition of the noted pop-concert series offers the sound of jazz - in the form of Dave Koz, Everette Harp, Spyro Gyra, Dianne Reeves, Kenny G, and Stanley Jordan.

Fusion artist Spyro Gyra performs ``South Beach''; Dave Koz offers ``Castle of Dreams,'' a track from his first album. Dianne Reeves sings ``Better Days,'' and Everette Harp does ``Let's Wait A While.''

In a salute to the season, Kenny G plays a music video from his new Christmas album, ``Miracles'': a saxophone rendition of ``Have Yourself a Merry Little Christmas.''

* SUNDAY

Hook (ABC, 8-11 p.m.): This 1991 film, receiving its network premiere as the ABC Sunday Night Movie, was passionately panned by several critics. But viewers may still be interested in sampling Steven Spielberg's splashy, modernized take on the classic Peter Pan story. If you can picture Dustin Hoffman in the title role, Robin Williams as Peter, and Julia Roberts as Tinkerbelle, you will already have some idea of the revised version, complete with music by John Williams.

Faces of Slavery (CNN, 9-10 p.m.): It may not carry the legal sanction it did in the 19th century, but slavery of the harshest and most evil kind abounds today, according to this edition of ``CNN Presents....'' London-based ``Anti-Slavery International'' maintains that some 20 million people are forced into bonded labor worldwide.

About 1 million of them are children placed into prostitution. The program finds that in Thailand, young girls are ``kidnapped and sold like cattle from one brothel to another.'' In India, meanwhile, a six-year-old boy laborer is beaten for not working hard enough seven days a week, 16 hours a day.

The program doesn't overlook the United States, either, where it claims thousands of workers in the Deep South are oppressed. The program probes the problem and looks for ways to curb and correct it.
