This one suddenly came to me while playing some Dire Straits...
The original is on piano, but this is nice to play on an acoustic as a 
solo folk song (the last verse can be played with some distortion to go
with the tone of the lyrics). I've tabbed this out in the key of G because
I naturally sing low and it's how I remember the song, but feel free to
transpose it to A if you can sing like Don. If so, then play as follows:

G becomes A
C becomes D
D becomes E
Em becomes F#m
Bm becomes C#m

That's it! Here's the song. Apparently, this was inspired by Don's
grandfather and his experiences farming. Think of it as a soft-rock 
counterpoint to "Foreclosure of a Dream" :-)

G (320003@1)                (can play Chere, (x32010@1)but not necessary)
I used to work for Harvester,
GI (320003@1)used to use my hands,
CI (x32010@1)used to build the tractors and the combines,
     Dthat (xx0232@1)plowed and harvested this great land...
      Em (022000@1)             C (x32010@1)
Now I see my handiwork on the block
Em (022000@1)         Bm (x24432@1)Everywhere I turn,
Em (022000@1)                           CAnd (x32010@1)I see the clouds cross the weathered faces,
      Bm (x24432@1)                DAnd (xx0232@1)I watched the harvest burn...

That's essentially it, as all the verses can be played with the same basic 
progression
(G / C / D followed by Em / C / Em / Bm / Em / C / Bm and end on D)

At the end (after "I don't see next year's crop"), return to the second
progression:

      Em (022000@1)           C (x32010@1)And I sit here in my back porch in the twilight, 
      Em (022000@1)              BmAnd (x24432@1)I hear the crickets hum...
      Em (022000@1)        CSit (x32010@1)and watch the lightning in the distance,
        Bm (x24432@1)          Dbut (xx0232@1)the showers never come...
  Em (022000@1)         C (x32010@1)I sit here and listen to the wind blow,
  Em (022000@1)         BmI (x24432@1)sit here and rub my hands,
  Em (022000@1)         CI (x32010@1)sit here and listen to the clock strike,
    Bm (x24432@1)                        C(end (x32010@1)on C) 
And wonder when I'll see my com-panion again..

That's about it. Economically and politically a bit dated, I guess, but
still packs a punch musically.
