I Know Why in Glenn Miller Orchestra

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 breezes sigh ev'ry evening
whispering your 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
I can see the sun when it's raining
Hiding ev'ry cloud from my view
And why do I see rainbows when you're in my arms?
I know why and so do you
I know why and so do you
