C        G7                           C           transpose to key of D 
  I keep a close watch on this heart of mine        C  -> D
            G7                     C                F  -> G
  I keep my eyes wide open all the time             G7 -> A7
             F                         C
  I keep the ends out for the tie that binds
                 G7              C
  Because you're mine I walk the line

  I find it very very easy to be true
  I find myself alone when each day is through
  Yes I'll admit that I'm a fool for you
  Because you're mine I walk the line

  As sure as night is dark and day is light
  I keep you on my mind both day and night 
  And happiness I've known proves that it's right
  Because you're mine I walk the line

  You've got a way to keep me on your side
  You give me cause for love that I can't hide
  For you I know I'd even try to turn the tide
  Because you're mine I walk the line
