Here's the chords (I hope it works in HTML!). I'll work on the midi if I can:

           D			D7	G		Em       
  1. When we were farmers we hauled in the harvest,        
  	C	D	       G	       
  and founded Thanksgiving Day.        
  	C	    D		Bm	Em       
  With food in the shed for the winter ahead,        
  		D	A	D-7       
  We would gather together to say:        
  		G		D       
  REFRAIN: Thanks for our health,        
      G		    D       
  Thanks for our heart,        
                   G		D		E        
  And the bounty that grows from the ground.        
  	      Am	D	 G	    Em	       
  With our loved ones near, we bless the year        
  	   C	       D	      G         
  That's brought us safely round.        
         D			D7	G		Em
