Nelson Eddy is in top form and fine voice and Rise Stevens, who has a voice like honey, is both charming and provocative. Musically, this is a treat and, unusually, it is also an entertaining film. They play a married couple who are leads in an operetta (lots of lovely music) with the husband suspicious of his wife's flirting and determined to test her by assuming another identity. She sees right through it and plays along to punish him.A real treat.
