Hope makes an obscure joke about the Chicago musicians union. He shows Crosby his snake-charmer instrument and says, "Hey, I've been playing this flute all night. Have to clear it with Petrillo." Petrillo was James Petrillo, the heavy-handed president of the Chicago Musician's Union.
In her 1980 autobiography, "My Side of the Road," (co-written with Dick McInnes), Dorothy Lamour relates how disappointed she was at not being asked to sing on the Decca album which re-created the film score. In Miss Lamour's place, the label recruited an artist under contract, Peggy Lee, to croon the sultry "Moonflowers" and then go upbeat with Bing Crosby and Bob Hope and on "The Merry-Go-Runaround" (both songs having music by Jimmy Van Heusen, lyrics by Johnny Burke).
In the movie, Bing Crosby makes reference to the Pittsburgh Pirates, which he was a minority owner of, and Bob Hope makes reference to the Cleveland Indians, which he was a minority owner of.
This was the only "Road" picture of the seven to be photographed in Technicolor. Ten years later, the British-made "Hong Kong" finale would revert to black and white.
