The song's title was initially also the title song of the film, before RKO owner Howard Hughes changed the title to Double Dynamite as a reference to co-star Jane Russell's famous cleavage.[1] The song is performed twice in the film: first in a scene where Sinatra and Marx are walking rapidly down a street, with Sinatra "trying to keep pace with Groucho Marx's trademark loping walk"; and then at the finale of the film, sung this time by Sinatra, Marx, and Russell.[2]
