Of cats and dames

The still is from 'Cat People' (the original movie from 1942 directed by Jacques Tourneur).
The song is 'Baby, It's Cold Outside' as here performed by Sammy Davis Jr and Carmen McRae (1957). The original score was created by Frank Loesser.
Go here to deciper the lyrics. For these lyrics are a gem. Constructed as (an overlapping) dialogue between a seductive predator and an indecisive dame, they will amuse you to no end.
Enjoy.
