That song 'I Only Have Eyes for You'....
...was written (by composer Harry Warren and lyricist Al Dubin) for this movie, and sung by Dick Powell and Ruby Keeler. I never knew that! I had always thought that the doowop version sung by The Flamingos in the late 50's was the original. Imagine my surprise upon watching "Dames" when I discovered that Dick Powell and Ruby Keeler did the original! Now THAT'S entertainment! lol
