This is a fictional film based on a fictional story about a real place in a real city , with real people playing the roles of some of the fictional characters and using their own name as the character name.
What transpires here has a character named Lester Robin (Bob Burns), a songwriter, and another character named Billie Shaw (Ann Miller), an aspiring dancer, striving to make good at Radio City (played by a sound stage in Hollywood), where a character named Kenny Baker (played by Kenny Baker)is already a star network singer. Also hanging around the premises are Harry Miller (Jack Oakie) and Teddy Jordan (Milton Berle), a Tin Pan Alley song-writing team who write songs for Radio City bosses Paul Plummer (Victor Moore) and Crane (Richard Lane.) Lester, an Arkansas show-boat performer, in his sleep composes songs which are excellent, but he is unconscious of the fact. He heads for New York City to take lessons from Miller and Jordan. Alas, Miller has gone stale but he learns the secret of Lester's sleep-time gift, and proceeds to copy the songs and market them as his own; his object being to finance the career of Miss Shaw, although she is in love with a fictional radio singer, the afore-mentioned Kenny Baker.
But through the success of Lester's songs that have been appropriated by Miller, she gets a dancing engagement, and her sister, Gertie Shaw (Helen Broderick), becomes romantically attached to Lester.
BUT...at a critical moment (a very relative term), Lester develops insomnia, and can't compose anymore since he isn't sleeping. HOWEVER...back in Arkansas, copies of his songs he produced in his sleep are discovered, with no mention of who was writing them down for him in Arkansas. Dancers Squenchy (Buster West) and Lisa (Melissa Mason)carry them to New York where Miller capitalizes upon them in a big way.
But Gertie, bless her, exposes the duplicity of Miller & Jordan, and Miller don't much care anyway as Billie has eloped with the fictional character named Kenny Baker, who just happens to be played by the real singer named Kenny Baker.
