A mere 5 million viewers tuned in Friday for the 8 p.m. bow of Rosie O'Donnell's variety show, "Rosie Live," on NBC. The show has been dropped from the network's schedule. Among those making appearances on the hourlong program - conceived as a throwback to such series as "The Carol Burnett Show" - were Alanis Morissette, Alec Baldwin, Clay Aiken, Ne-Yo and Liza Minnelli. It earned a 1.2 preliminary rating among adults 18-49.
