Frank Sinatra & The Tommy Dorsey Orchestra - 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 burn It's not the book I lent you that you 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, remember it's my heart Remember It's my heart This heart with which so willingly I part It's yours to take, to keep or break, but please, before you start Be careful, be careful Be careful it's my heart!
