Well I've been watchin' you   And you've been watchin' her   You looked like you saw a ghost    The moment she walked in    I knew there was someone else    Before I came along   I've often wondered who she was   And was she really gone      Who's she to you    And where does that leave me   Is she still in your heart   Or just a memory   If she says hello   Will you tell me goodbye   Who's she to you   And darlin' who am I      The looks you're giving her   Are doin' things to me   You say there's no reason at all    For my jealousy   As long as there's a little smoke   A fire's never cold   If history repeats itself   What does our future hold      Who's she to you    And where does that leave me   Is she still in your heart   Or just a memory   If she says hello   Will you tell me goodbye   Who's she to you   And darlin' who am I      If she says hello   Will you tell me goodbye   Who's she to you   And darlin' who am I
