Ernie Kovacs music.
The music played during the early nightclub scene has a lot of similarity to the closing theme of the old Ernie Kovacs show. A jazzed up version and of course without the funny sound effects.
I wonder if this restoration is using new music or if this is actually the score that the theater piano players would have used.
edit: Found on youtube the Kovacs piece to which I referred.
Quoting one of the youtube comments "I remember this when I was a kid. I used to watch Ernie Kovacs. Years later, I heard George Gershwin's Rialto Ripples.. This theme is an altered version of it."
