It Could Happen To You 
From the film "And the Angels Sing", Johnny Burke, Jimmy Van Heusen

Do you believe in charms and spells, in mystic words and wands and wishing wells?
Don't look so wise, don't show your scorn; watch yourself, I warn you.

Hide your heart from sight, lock your dreams at night.
It could happen to you.
Don't count stars or you might stumble,
Someone drops a sigh, and down you tumble.

Keep an eye on Spring, run when church bells ring.
It could happen to you.
All I did was wonder how your arms could be
And it happened to me!
