The song I Don't Know Why is performed by Nana Mouskouri .
I don't know why the sky is so blue
And I don't know why I'm so in love with you
But if there were no music then I would not get through
I don't know why
I know these things, but I do
I don't know why but somewhere dreams come true
And I don't know where but there will be a place for you
And every time you look that way I would lay down my life for you
I don't know why
I know these things, but I do
I don't know why but some are going to make you cry
And I don't know how but I will get you by, yes I will try
Oh they're not trying to cause you pain they're just afraid of loving you
I don't know why
I know these things, but I do
I don't know why
I don't know why
I don't know why
I know these things, but I do
I don't know why the trees grow so tall
And I don't know why, well I don't know anything at all
But if there were no music then I would not get through
I don't know why
I know these things, but I do
I don't know why
I know these things, but I do
