Sweetheart of mine I've sent you a Valentine.
Sweetheart of mine, it's more than a Valentine.
Be careful it's my heart.
It's not my watch you're holding it's my heart.
It's not the note I sent you that you quickly burned.
It's not the book I lent you that you never returned.

(Linda)
Remember, it's my heart.
The heart with which so willingly I part.

(Both)
It's yours to take to keep or break,
but please before you start be careful it's my heart.

(Jim)
Remember it's my heart
the heart with which so willingly I part.
It's yours to take to keep or break,
But please, before you start,
Be careful, it's my heart.
