This is from the hit 1940 Broadway stage show Pal Joey, starring Gene Kelly (a big break for him), June Havoc (who was immortalized as "Baby June" in "Gypsy") and Van Johnson.

When Hart died, Rodgers wrote with Oscar Hammerstein such shows as South Pacific, The King and I, and Sound of Music. (thanks, Janna – Los Angeles, CA)
