If I Only Had a Heart

"If I Only Had a Heart" was a song from "an old Earth movie", The Wizard of Oz, which Ira Graves referenced when he met Data. As Data did not understand, Graves explained how the song was an allegory for Data's own predicament: "A mechanical man wants a heart but learns that he was Human and had one all along."

Lyrics
The song, "If I Only Had a...", had three refrains using the same tune with different characters and lyrics. The Tin Man's was as follows:

When a man's an empty kettle

He should be on his mettle

And yet I'm torn apart

Just because I'm presumin'

That I could be kind-a human

If I only had a heart.

I'd be tender, I'd be gentle

And awful sentimental

Regarding love and art

I'd be friends with the sparrows

And the boy who shoots the arrows,

If I only had a heart.

''Picture me ... a balcony ...''

Above a voice sings low&mdash;

Wherefore art thou, Romeo?

I hear a beat.

How sweet!

Just to register emotion.

"Jealousy", "devotion"

And really feel the part

I could stay young and chipper

And I'd lock it with a zipper

If I only had a heart.

If I Only Had a Heart
