You Took the Words Right Out of My Heart (1938)
Made by Max Fleischer as part of Paramount's "Screen Songs" series, and combining cartoon action with live performers. Opens as a cartoon showing kidding newsreel-type shots of a lion tamer, a tight-rope walker, an actor and a sweepstakes winner as caught by a candid(animation) camera. Ends with a cut to live action with Jerry Blaine and his Streamline Rhythm Orchestra playing while band vocalist Phyllis Kenny sings the title song.
