A great song! A friend of mine sings this one every now and then. Unfortunately, she sings it unaccompanied, so I couldn't ask her for the chords. But I guess you could use this:

[C]Johnny Miner [Am]you were born,
[F]never to see the [Am]rising dawn,
[F]now it's time that [C]you were [Am]gone,
[F]farewell Johnny [G]Miner

These are very simple chords, nothing fancy, but it worked for me. If you think that these chords are wrong, please let me know.
