In the '30s, the New Orleans vocal trio known as the Boswell Sisters was hot -- so hot that the three stunning young women in the group inspired the Andrew Sisters. But the trio is all but unknown today.

Now, three Broadway divas -- Dee Hoty (The Will Rogers Follies and next season's Footloose), Sally Mayes (She Loves Me) and Nancy Opel (Triumph of Love) -- are re-creating the sisters' closely harmonized blend of music in a revue, "Rhythm on the Rainbow: The Hot Harmonies of the Boswell Sisters," at the nightclub Rainbow & Stars in NY's famed Rainbow Room.

But you better make tracks to Rockefeller Center, because the revue ends Sat. Mar. 28.

Hoty, Mayes and Opel play the siblings -- Connee (who went on to a solo career and whose honeyed sound can be heard on many an old radio broadcast at NY's Museum of TV & Radio), Martha and "Vet" -- and perform 20 songs associated with the trio including "Heebie Jeebies," "When I Take My Sugar to Tea," "Everybody Loves My Baby" and "Yes Sir, That's My Baby."

The revue's co-creators are Stuart Ross and Mark Hampton. Shows are at 8:30 and 11 PM. Cover for both shows is $40 and dinner is required for the early show. For more information, call (212) 632-5000.
