I'm so crazy about you

"I'm crazy about you
I'll give you all my love
Yes I'm crazy about you
Night and day, day and night
I'll be your heart's salvation

Hey baby, let's stay together
Let's make it now and forever
I want to show it and shout it
And tell the whole world about itI thought it never could happen
I thought you never would see me
You run a lovin' locomotive
You make my needs very primitive
