Sunny, yesterday my life was filled with rain
Sunny, you smiled at me and really eased the pain
Oh, the dark days are done

My sunny one shines so sincere

I love you
Dusty Springfield
Sunny, thank you for that sunshine bouquet
Sunny, thank you for the love you brought my way
You gave to me your all and all
Now i feel ten feet tall
Sunny one so true
I love you
Sunny, thank you for the truth you let me see
Sunny, thank you for the facts from a to z
My life was torn like windblown sand
And then a rock was formed when we held hands
Sunny one so true
I love you
Sunny, thank for that smile upon your face
Sunny, thank you for that gleam that flows with grace
You're my spark of nature's fire
You're my sweet complete desire
Sunny one so true
I love you
Sunny, yesterday my life was filled with rain
Sunny, you smiled at me and really eased the pain
The dark days are done
The bright days are here
My sunny one shines so sincere
Sunny one so true
Sunny one so true
Sunny one so true
I love you
