Obviously an attempt to feature Grace Moore, whose career was in decline. She got top billing over Cary Grant and spent about half the movie singing opera songs. Subtract the singing, and the movie was mildly amusing until the festival scene where it got silly, with Jimmy willing to divorce her when she insists on singing at the festival and then Louise willing to not sing at the festival to stay married to Jimmy and then suddenly it was OK to sing at the festival AND stay married. Cary had some moments of classic Cary Grant, but that wasn't enough to save the movie. It was one of those plots which would exist if the two people in love actually told the truth, listened to each other, and believed each other.
