Rosemary Clooney - Be Careful, It's My Heart lyrics

Be careful, it's my heart It's not my watch you're holding, it's my heart It's not the note that I sent you that you quickly burned It's not the book I lent you that you'll never return 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
