Kathryn Grayson was an American actress, best known for her work in film musicals during the 1950s and on stage, mainly in opera, in the 1960s, although she certainly had a career in film and on television on either side of those two decades. Her best remembered films are probably the heavily criticized 1951 remake of Show Boat and the more popular film version of Kiss, Me Kate (1953). In the 1960s, she was a replacement for Julie Andrews in Camelot and starred in operas like as La Bohème and Madama Butterfly. Here is a clip from another of her films, Anchors Aweigh (1945), the “Waltz Serenade”:
