Here’s a Wednesday night TV special we bet Barbara Walters won’t be watching: Rosie Live, which stars Rosie O’Donnell and features a mishmash of Broadway dancers, celebrity appearances, comedy sketches, and musical performances. The special will be a test of the viability of the variety genre, which is earning new attention as ratings falter across the board. (The Osbournes and John Mayer are set to launch similar programs). Original variety queen Carol Burnett says, "I'm happy that the V word isn't so nasty anymore." Should Rosie Live sail to the top of the Nielsen charts, her special could become a weekly series.
