Gilda Radner, played Rosanna Roseannadanna on Sat. Night live
"Roseanne Roseannadanna" was one of several recurring characters created by Gilda Radner who appeared in the "Weekend Update" segments of the early seasons of the NBC comedy television show, Saturday Night Live.
Like Radner's earlier character, Emily Litella, Roseanne was brought in to give editorial replies to current issues. Unlike Emily Litella, however, Roseanne Roseannadanna was not meek or apologetic, but rather brash and tactless. The character was based on Rose Ann Scamardella, a former anchorwoman of WABC-TV's Eyewitness News in New York City. The character later appeared in Radner's live one-woman shows.

I miss Glida Radner I loved watching her too
