I Know Why (And So Do You)
 作词 : Mack Gordon
 作曲 : Harry Warren
why do robins sing in December
long before the Springtime is due
And even though it's snowing，violets are growing
I know why and so do you
why do breeze sigh every evening
whispering there name as they do
And why have I the feeling stars are on my ceiling
I know why and so do you
When you smile at me
I hear gypsy violins
when you dance with me
I'm in heaven when the music begins
Ican see the sun when it's raining
Hiding every cloud from my view
And why do I see rainbows when you're in my arms
I know why and so do you
