Glenn Miller, Paula Kelly & The Modernaires i know why and so do you

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
