For Older Dancers, Works With a Timeless Gloss.

Paradigm, the group formed 10 years ago by Gus Solomons Jr. with Carmen deLavallade and Dudley Williams, has always seemed like a good idea on paper. But this company, created for and by older dancers, hasn't always produced work equal to the talent. In the troupe's latest program, presented on Thursday at Dance Theater Workshop as part of the SummerDANZ series, Paradigm began with a bang: Kay Cummings's ''Stayin' Alive,'' set to the Bee Gees' disco hit of the same title. Mr. Solomons, Valda Setterfield and Mr. Williams, wearing hospital gowns and pushing IV stands, took shaky sideway steps across the stage. Occasionally pointing a tired finger in the style of John Travolta or flashing a manic grin, the dancers, notably the hilarious Ms. Setterfield, sparkled like vaudeville stars.
