Most musicals live or die by their musical numbers, and this is especially true with The Lullaby of Broadway. Not that Lullaby doesn't have a story; there's plenty of plot here, but not really any plot development. Instead, the details of the plot are dispensed within as few lines as possible, to make room for the next big socko number. This skimpy approach also leads to a lack of character development, which would be less of a problem if the songs were geared toward filling in the blanks. Instead, they're mostly geared toward entertaining the viewer -- and Lullaby is lucky that the songs do this so darn well! From the title song to "Please Don't Talk About Me When I'm Gone" to "Somebody Loves Me," there's nary a clunker in the bunch. And since they're performed by the delectable Doris Day and the affable Gene Nelson, most viewers will be willing to forgive Lullaby its many shortcomings. Certainly Day is in top form, loaded with charm and innocence and full of delightful voice, and Nelson, Gladys George, S. Z. Sakall, and the rest of the cast provide wonderful support. For totally mindless entertainment, Lullaby is choice.
