Young At Heart - Frank Sinatra 

Fairy tales can come true
It can happen to you
If you're young at heart
For its hard, you will find
To be narrow of mind
If you're young at heart

You can go to extremes with impossible schemes
You can laugh when your dreams fall apart at the seams
And life gets more exciting with each passing day
And love is either in your heart or on its way

Don't you know that its worth every treasure on earth
To be young at heart
For as rich as you are, its much better by far
To be young at heart

And if you should survive to a hundred and five
Look at all you'll derive out of being alive
Then here is the best part
You have a head start
If you are among the very young at heart
