Sunshine Superman lyrics

Sunshine came softly through my window today
Could've tripped out easy but I've changed my ways
It'll take time I know it but in a while
You're gonna be mine I know it, we'll do it in style

'Cause I made my mind up you're going to be mine
Any trick in the book now baby that I can find
Everybody's hustlin' just to have a little scene
You stood on the beach at sunset, do you remember when?
I know a beach where baby it never ends
'Cause I made my mind up you're going to be mine,
Superman or Green Lantern ain't got nothin' on me
I can make like a turtle and dive for pearls in the sea
Oh you can just sit there thinkin' on your velvet throne
You got all the rainbows you can have for your own
When you've made your mind you're going to be mine
