Lyrics:

You gotta have heart
All you really need is heart
When the odds are saying you'll never win
That's when the grin has to start

You gotta have hope
Mustn't sit around and mope
Nothing's half as bad as it might appear
Wait'll next year and hope

When your luck is batting zero
Get your chin up off the floor
Mister, you can be a hero
You can open any door
There's nothing to do but to do it

You've got to have heart
Miles 'n miles 'n miles of heart
Oh, it's fine to be a genius, of course
But keep that old horse before the cart
First, you gotta have heart
