I Know Why 歌詞

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!
