A year before her eponymous variety show, Carol Burnett was joined by fellow red-headed comedienne Lucille Ball and Broadway star Zero Mostel for the hilarious 1966 television special “Carol + 2.” Watch as Carol and Lucy deliver a hilarious spin on Carol’s classic Charwoman character, Mostel belts out a rendition of “If I Were a Rich Man,” and more. Then, the 1972 TV-movie “Once Upon a Mattress” is a musical comedy adaptation of “The Princess and the Pea” starring Burnett, Ken Berry, and Bernadette Peters. Finally, Carol introduces the first appearance of the Charwoman in the 1963 TV special “An Evening with Carol Burnett.” 158 min. total. Standard; Soundtrack: English.
