Escaping from the hoods at the wedding by bursting through the crowd, Scat shouts "Come on Blanchard" and Hotlips replies "Block 'em Davis". The audience would have recognized the reference to Felix Blanchard and Glenn Davis, former Army star running backs. As team-mates from 1944 to 1946, they were referred to as "Mr. Inside" and "Mr. Outside." Blanchard had won the Heisman Trophy in 1945 and Davis in 1946, the year before the movie was released.
This film contains the last on-screen singing performance by The Andrews Sisters, who share with Bing Crosby the saucy Latin-swing hit, "You Don't Have to Know the Language" (music by Jimmy Van Heusen, lyrics by Johnny Burke). This number was revived splendidly by Lena Horne on two RCA Victor albums: "Songs by Burke and Van Heusen" (released in 1959), and "Lena at the Sands" (recorded live in Las Vegas, November 3-5, 1960).
Disembarking from the ship, Bing Crosby tells sinister Gale Sondegaard "I'll listen for you on Inner Sanctum". Radio's "Inner Sanctum Mysteries" debuted in 1941 and featured gruesome stories and spine-chilling characters.
On the Decca Records boxed album of selections from the Johnny Burke-Jimmy Van Heusen film score, substitutions were made in the way that two songs were presented. Bob Hope was under contract to Capitol Records at this point, so the Hope-Bing Crosby duet of the agile city tune, "Apalachicola, FLA," was semi-recast on the album by teaming Bing with The Andrews Sisters, already guest-starring in the movie. Dorothy Lamour, recording for the Coast label at this point, delivered in this feature the comically sly "Experience," which was transformed by Decca into a pairing of Mr. Crosby and Nan Wynn, who did not participate in the picture.
The gag in which Bob Hope and Bing Crosby pose as barbers and accidentally shave the gangster's mustache off is copied from the 1931 Marx Brothers' film "Monkey Business," made by the same director, Norman Z. McLeod.
