Himself
Conceited singer Garry Mitchell refuses to renew his radio contract, so agent Doug Blake decides to find a new personality to replace Garry. In New York, he finds Martha Gibson, a single mother with a great voice. He arranges for her to move to Hollywood, but then has a problem trying to sell her to the show's sponsor. Doug tries every trick he can think of to make Martha a star, and as the two work more closely, he falls in love with her. Complicating matters further is when Martha meets and becomes attracted to Garry.
Band Leader Frankie Carle (as Frankie Carle and His Piano)
Airline hostess Ann Parker is fired for being undignified when she sang to calm the passengers during a storm. Mike Connors, publicity man for Frankie Carle's orchestra, invites her to try out as the band's vocalist since the regular singer, Mary Lou, had just quit the band on the eve of an engagement at a swanky New York night club. Encouraged by her boyfriend, Steve Roberts, Ann lands the job and assumes the name of "Mary Lou", a trademark almost for Frankie Carle singers. But the departed Mary Lou shows up and threatens to sue if she is not rehired. Ann returns to her former job. Meanwhile, Steve locates the woman who was the original Mary Lou with the band, and urges Mike to keep the current Mary Lou off the bandstand until he can return with Ann.
