I've Got The World On A String Lyrics

I've got the world on a stringI'm sitting on a rainbowGot the string around my fingerWhat a world, what a life - I'm in loveI've got a song that I singI can make the rain go Any time I move my fingerLucky me, can't you see - I'm in loveLife's a wonderful thingAs long as I hold the stringI'd be a silly so-and-soIf I should ever let her go
