Although he frequently downplayed his singing ability, Fred Astaire was instrumental in introducing classic songs by Cole Porter, George Gershwin and Jerome Kern. He was admired for the way he interpreted a tune, his phrasing and diction, so much that songwriters had him in mind when they created their music. This video, from the 1936 RKO film Swing Time presented Kern's 'The Way You Look Tonight' to the music loving public.
