knock on wood song from Casablanca

Hey my friends!

I would like to know is it possible to get somewhere that song which is played by Sam at Rick`s and goes like `Say, who’s got trouble? - We got trouble -. How much trouble? - Too much trouble -. Well now don’t you frown - Just knuckle down and Knock on Wood...`

BUT exactly like this version as we can hear in film, ok?

Thanks a lot!
