"Thinking of You" is a popular song, composed by Harry Ruby with lyrics by Bert Kalmar.
It was introduced in the Broadway show, The Five O'Clock Girl (1927) when it was sung by Mary Eaton and Oscar Shaw.

In the film, Vera-Ellen (dubbed by Anita Ellis) sings the song which then develops into a major dance routine with Fred Astaire.
