Thanks to my friend Mark for telling me about the Sonovox - that's the instrument he thinks is at the beginning of "Night Lover" (posted previously). The Sonovox is kind of a precursor to the talk box tube (Pete Drake "Forever", Frampton Comes Alive, etc.). This video clip is from the end of a 1940 comedy called "You'll Find Out."
I try to avoid unnecessary hyperbole in speech and writing, but...
THIS IS THE BEST VIDEO I'VE EVER SEEN. (don't miss the little dog!)
Mark also recommended a few other cool Sonovox videos, see his comment in the "Night Lover" thread.
