I'm gonna lock my heart (and throw away the key)

I'm gonna lock my heart
And throw away the key
I'm wise to all those tricks you played on me
I'm gonna turn my back on love
Gonna snob the moon above
Seal all my windows up with tin
So the love bug can't get in
Park my romance right alone the curb
Hang a sign upon my heart
"Please don't disturb"
And if I never fall in love again
That's soon enough for me
I'm gonna lock my heart
And throw the key

And it I never tall in love again
That's soon enough for me
I!m gonna lock my heart
And throw away the key

I'll never fall in love again
I'm gonna lock my heart
And throw away the key
