When a synth's a talking spaceplane
They shouldn't be complainin'
And yet I'm torn apart

Just because I'm presumin'
I could be a better iakan
If I only had a heart

I'd be tender, I'd be gentle
And awful sentimental
Regarding love and art

I wouldn't be so scary
Would-be friends need not be wary
If I only had a heart

Flyin' high
About the sky
Above a voice sings low

(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

Alternate version.
