Wake Up and Live (1937)

Built around the publicity "feud" between newspaper-radio-gossip spreader Walter Winchell and band leader Ben Bernie, a radio star, Alice Huntley (Alice Faye), who does an advice-and-inspiration program, helps a mike-shy singer, Eddie Kane (Jack Haley) to success by tricking him into singing with Bernie's orchestra. Winchell uses it to expose Bernie as the trickster. But Kane becomes a great hit with the radio public, and falls in love with Alice. And Bernie and Winchell shake hands to show there's no business like show business and fabricated feuds.
