The voice from the screen

""An early demonstration of talking movies"--Videodisc jacket. Edward B. Craft leads the audience on a tour of the studios of the Vitaphone Corporation in order to demonstrate the Vitaphone process of recording a sound disc synchronously with a moving image picture, and then synchronously playing both back to a motion picture theater audience. The camera booth, the recording booth, and the projection booth are all shown. As part of the demonstration, a Vitaphone short entitled Witt & Berg, premiere entertainers, is filmed, featuring two ukulele players who perform My hula baby, I used to be so sentimental, and I don't mind being all alone when I'm all alone with you. Could Witt be Bob Witt?"
