Teddy Taylor (David Manners) leads a struggling band looking for a big break. That break comes through serendipity when a drunk (Guy Kibbee) dances past the band stand and mockingly hands him a megaphone to project. In no time he's "making the charts and the girls are tearing him apart." With overnight success Teddy's demeanor goes from team player to prima donna causing a huge rift between him band members, agent and girl friend (Ann Dvorak).
Crooner is a rather benign story about the pitfalls of instant stardom and the virtues of humility. The handsome Manners is surprisingly effective in the transitioning and there's some light comedy and catchy tunes to keep one's attention. Still, I can't help but wonder if this is a veiled attempt to expose the out of control ego of one of the day's big time crooners. The megaphone prop would suggest Rudy Vallee but it was no secret back then that Bing Crosby dumped his back up band and went on to solo super-stardom.
