I know something about this. I bought a crazy English magazine with appreciation of this movie. Didn't Jones say that she would choose vodka and tea Khan in this plot of the movie? I guess this is Chakahan's song. There is a note at the bottom of the book:

Chaka Khan is a famous American jazz singer. 1953 was born in Illinois on March 23rd. His most famous album is Prince, and the title song is My Feelings for You.
