After you've seen this, you can't say that Bing Crosby didn't do his best--in this film and in" Birth of the Blues"--to give credit where credit is due for the origins of truly American music. Here he is teamed with Mary Martin, who starred in "South Pacific" when it played on Broadway. Crosby did a lot to popularize a smooth white, if you will, form of jazz that has helped it endure to this day and to claim its proper place in the canon. His version of the title song is a classic. --Musicals on the Silver Screen, American Library Association, 2013
