On its first (and possibly only) theatrical run, this film was shown as the second feature on a double bill with the 1962 re-release of Lady and the Tramp (1955).
The coat of arms of the Republic of Austria is an Eagle crest. Disney requested the Austrian government to allow the Vienna Boys Choir to wear the Eagle crest on their tunics for the film. The request was granted and Eagle crest has been a part of their attire ever since. In the movie, the Eagle crest is visible on the Choir's black tunics used for performances in Austria, but not on their white traveling tunics worn in the last scene set in Australia. Apparently, there was not adequate time to put the crests on all of the tunics, because their traveling tunics have had the crest since that time.
Many of the songs are sung in German, but the songs are not included in the DVD subtitles.
When the film was released in 1962 with a 1.75:1 aspect ratio, it was generally cited as having a 93 minute run time. It was released in 1985-6 with a 1.33:1 aspect ratio on VHS and Betamax video cassettes for sale to video rental stores. It was released in December, 2010, on DVD exclusively for sale to Disney Movie Club members with a 1.33:1 aspect ratio and a run time of "approximately 93 minutes" listed on the case, but an actual DVD run time of 1 hour, 29 minutes and 44 seconds that is approximately 90 minutes. The input source material provided to the DVD manufacturer contained audio distortions and slight video distortions from 0:24:58 to 0:25:38 (40 seconds) so the glass master, and all DVDs produced from it, contained the 40 seconds of distortion. When the distortions were discovered they were considered too insignificant to reissue the DVDs.
The 32nd Live-Action film produced by Disney.
