Intro: G G-Bb-G C-Bb (x2) C Bb G Been a long time coming And the cards were stacked C G It's been a long hard road to hell and back Your love meant trouble C G You won every hand, I lost every bet C Now you think that I G Should've Known Better C Now I think that I G Should've seen it come C Bb My heart sank G When I read that letter C D Sank like a stone, sank like a stone G Cup of cold coffee Yesterday's mail C A bad love like this is always G Bound to fail G G Bb G Your love meant trouble from the day we met C Bb C If you want your things G They're on the front step C Now you think that I G Should've Known Better C Now I think that I G Should've seen it come C Bb My heart sank G When I read that letter C D Sank like a stone, sank like a stone. Mandolin Solo (use chords from verse) G All alone in my kitchen All alnoe in my head C Some things you can't take back G Once they've been said G I don't know what This love is for C All I know is I G Don't want it anymore C Now you think that I G D Should've Known Better C Now I think that I G Should've seen it come C Bb My heart sank G When I read that letter C D Sank like a stone, sank like a stone. I did this from a live show. It's pretty darn accurate.
