The boys of O-Town endure grueling photo sessions and style makeovers on Making the Band (9:30 p.m. Fri., ABC). American descendants of African slaves confront their past on 20/20 (10 p.m. Fri., ABC).

On a rerun of The Simpsons (8 p.m. Sun., Fox), Moe undergoes cosmetic surgery and becomes a soap opera star. On Sex and the City (9 p.m. Sun., HBO), Carrie gets a new boyfriend (John Corbett of "Northern Exposure"), and this one's going to stick around awhile. Queen Latifah goes under the microscope on Behind the Music (9 p.m. Sun., VH1).
How thoughtful of NBC to run a three-hour Freaks and Geeks marathon (8 p.m. Sat., NBC), now that the show is canceled. Where should we send our thank you notes? Still, these are the series' three remaining first-run episodes, so set the VCR and spend a geeky night by the tube paying last respects to one of the finest high school comedy-dramas that ever lived. NBC's only crime: it would have preferred "That '70s Show." The new cable movie Longitude (8 p.m. Sun., A&E) stars Jeremy Irons and Michael Gambon in an adaptation of Dava Sobel's bestseller about the invention of the chronometer to aid navigation at sea.
