and the difference is you

What a difference a day made
Twenty four little hours
Brought the sun and the flowers where there used to be rain
My yesterday was blue dear
Today I'm a part of you dear
My lonely nights are through dear
Since you said you were mine

Oh, what a difference a day made
There's a rainbow before me
Skies above can't be stormy since that moment of bliss
That thrilling kiss
It's heaven when you find romance on your menu
What a difference a day made
And the difference is you
