With Sam Warner he produced the soundtracks for Don Juan and The Jazz Singer. (That's a very brief summary and leaves a lot out!)I would be grateful for any information your organization might have about the sound recordings during this period. During the experimental process he personally was recorded on many trial discs at the Labs and I would love to know if any remain.Also, Stan Watkins was in charge of recording at Columbia in the early '20s and recorded Bessie Smith and Eddie Cantor. I have been unable to find out where to look for Columbia archives of this period - I usually get sent way back to 1960!I'd be glad of anything you can suggest which might be of help in my research.Thank you in anticipation.Barbara (Watkins) WitemeyerAlbuquerque, NM505-268-7579 =
