Guy Bolton and P.G. Wodehouse's book for this zany "roaring '20s" show (it opened in 1926) came complete with mistaken identities, bootlegers, and, of course, triumphant love. But what makes it endearing to this day are the Gershwins' fanciful and witty songs. In the title role, soprano Dawn Upshaw confirms that she's one of the few classically trained singers who can "cross over" and sound natural in a musical ("Maybe," "Someone to Watch over Me"). The ace cast also includes Kurt Ollmann ("Dear Little Girl," "Do, Do, Do" with Upshaw), Robert Westenberg, and Liz Larsen. The Orchestra of St. Luke's, conducted by Eric Stern, works wonders with the fully restored score, and swings handsomely on "Clap Yo' Hands." Nicely recorded and packaged (lyrics included!), this is a keeper. --Elisabeth Vincentelli
