At one point Donald O'Connor commiserates with Bing Crosby, "You've got yourself a case of moonburn, huh?" "Moonburn" is the title of a Hoagy Carmichael song added to the 1936 film version of Anything Goes (1936) also starring Crosby.
Although both films and the original stage musical take place on an ocean liner, the plot of this version of "Anything Goes" has nothing to do with the plot of the 1936 film version of the musical, or, for that matter, with the show.
In the title song Anything Goes, the line is "Now only use FOUR letter words, but in the movie Mitzi Gaynor sings "Now only use THREE letter words." The Production Code Administration, or the Breen Office would have banned "FOUR letter words" on the grounds of implied obscenity.
Anything Goes opened at the Alvin Street Theater on November 21, 1934 with Ethel Merman and ran for 420 performances.
