Moon River, wider than a mile,
I'm crossing you in style some day.
Oh dream maker, you heartbreaker,
wherever you're going I'm going your way.
Two drifters off to see the world.
There's such a lot of world to see.
We're after the same rainbow's end--
waiting 'round the bend,
my huckleberry friend,
Moon River and me.
