Thanks for mentioning When Morning Breaks, Tattie. I didn't notice its usage of bVII and bIII chords until you reminded me of that. I've posted the chords to the song on my website here:

               F               D
  When morning breaks, I'll be gone.
               F               D     G
  When morning breaks, I'll be gone.
                 D               F
  And where I go, I do not know.
                               D
  When morning breaks, I'll be gone.
  
  
                C           D
  The drums are rolling for war.
                C           D 
  The drums are rolling for war.
                G      C                D
  The lines are forming to wait for the morning,
                  C              A     D
  To wait for the cruel cannons' roar!
  
  
               F               D
  When morning breaks, I'll be gone.
  

It reminds me of another Paxton song - Jimmy Newman. F chord is frequently used, while the song itself is in the key of E. It's a rare occasion where a bII chord is used. I've come across some songs with bIII, bVI or bVII chords, but I believe Jimmy Newman is the only song I've ever played that uses a bII chord. Maybe there are more that I've listened to but didn't notice.
