"...a voice within me keeps repeating: you, you, you. Night and day you are the one. Only you beneath the moon and under the sun.
Whether near to me, or far - it's no matter darling where you are. I think of you night and day.
Day and night, why is it so?
That this longing for you follows wherever I go...in the silence of my lonely room, I think of you.
...a hungry yearning, burning inside of me and its torment won't be through till you let me spend my life making love to you,
day and night, night and day..."
- written by Cole Porter, circa 1932
Ella Fitzgerald sings one of my favorite versions...
