The "Calamity Jane" stage musical originated as a live adaption of "Calamity Jane", the 1953 Warner Bros. movie musical with Doris Day.  First produced in 1961, the stage musical "Calamity Jane" features six songs not heard in the movie.  According to Jodie Prenger, star of the "Calamity Jane" 2014 - 15 UK tour, the songs added for the stage musical had been written for but not included in the "Calamity Jane" movie ("Love You Dearly" had been used in the 1954 Doris Day musical film "Lucky Me").
