I wish I had a time machine and could go back to the old Met and hear some of these singers like Galli-Curci and Lily Pons, who had voices the size of gnats. Nowadays a straight coloratura would never be given Violetta to sing. I'm not even sure one would sing Lucia. They still sing Gilda, and by Act II, it looks like a silent movie. as no one can hear them.
Anyway, Lily Pons was a huge international breakout opera star who made three films for RKO in the '30s. She also did advertisements and gave concerts. Here, she plays a singer, Nikki Martin, a Parisian without a passport who takes off on her wedding day and winds up meeting musician Windy McLean (Gene Raymond) who plays with a band, the 'McLean Wildcats.' Nikki falls for him and stows away on the ship that takes him and his band back to America. Authorities find her, lock her up, and fire the band, which was supposed to play on the ship. Nikki escapes once the ship reaches New York and turns up at the Wildcats' apartment.
Windy's girlfriend, Clair (Lucille Ball) arrives and has a job for them at a roadhouse, which gets them out of town and away from the authorities, who want to bring them to justice for hiding Nikki. When Clair is injured, Nikki becomes very popular as the band's singer. Clair reports them, and soon, they're on the run again.
The band players (Jack Oakie, Hermann Bing, and Mischa Auer) are funny and lively. The film contains lots of music of all kinds. At the end, Pons sings one of her signature roles, Rosina in "The Barber of Seville." Today that role is sung by a mezzo-soprano.
Pons had excellent coloratura technique (but no trill) and, like most female singers of that era, backed off the high notes. It has to do with their training and the type of sound that was considered acceptable. She had a high F and was known for Lakme, an opera which isn't done much anymore.
This is an entertaining film that gives one a chance to see one a really big opera star of the day, during a time when opera was much more a part of the culture. Pons sang into her seventies and, even when I was a child, was still very well known.
