That 30 minutes includes the dance numbers by Ann Miller and The Champions (indeed they were). The other 15 minutes is at the end of the film, a gorgeous fashion show designed by Adrian. It's the ultimate display of fantasy 50s feminine fashion. The designers and runway models of today should view this on how it should be done rather than the current crop of strident and pouting stringbeans who posture and pose in the drab and dreary unimaginative rags that pass as au courant fashion.
Grayson and Keel didn't really gel in this confection. Grayson always seems to be pouting, but that seems to have been her basic acting style. Keel is a bit stiff here, but his singing is right on the money. Red Skelton was quite funny back then and hugely popular; alas, his type of humor seems to have lost its appeal over time. Zsa Zsa was never the consummate actress like her sister, Eva (!!!) but her presence here added a daffy charm that soon became the Gabor sisters' trademark.
Still, the star of this flick is Adrian with his array of fab 50s feminine fashions that are definitely "Lovely To Look At". The gowns were especially spectacular and they inspired many a prom dress back then; also, debutante balls, weddings, and beauty pageants.
Glad to see that this film has finally become available. For many years, I believe it had problems being released because of copyrights held by the Jerome Kern estate.
