The song was originally written for a 1932's film, "Love Me Tonight".
It has a 32-bar chorus in ABAC form. Alec Wilder, in his book American Popular Song: The Great Innovators 1900-1950, calls it "a perfect song."
Isn't it romantic? Music in the night, a dream that can be heard. Isn't it romantic? Moving shadows write the oldest magic word. I hear the breezes playing in the trees up above While all the world is saying you were meant for love.
Isn't it romantic Merely to be young on such a night as this? Isn't it romantic? Every note that's sung is like a lover's kiss. Sweet symbols in the moonlight, Do you mean that I will fall in love perchance? Isn't it romance?
