Dom--
I know you've been deluged with words. Here are two different settings for D as a D. My none-too-discriminating ear heard it the first way, but I have much more fun with #2.

/G/Well, come on, you young fellows, so /C/young and so /D7/fine;
Don't /G/seek for your fortune way /C/down in the /G/mine.
It'll form as a habit and /C/seep in your /D7/soul,
Till the /G/blood in your body runs /C/black as the /G/coal.

It's /D7/dark as a dungeon and /G/dank as the dew,
Where the /D7/danger is double, and /G/pleasures are few.
/G/Where the rain never falls, and the /C/sun never /D7/shine;
It's /G/dark as a dungeon, way /C/down in the mine.

/G/Well, come on, you young /Em/fellows, so /C/young and so /A/fine,
Don't /G/seek for your /Em/fortune way /C/down in the /D/mine.
It'll /G/form as a /Em/habit and /C/seep in your /A/soul,
Till the /G/blood in your /Em/body runs /C/black as the /G/coal.

It's /D/dark as a dungeon and /C/dank as the /G/dew,
Where /D/danger is double, and /C/pleasures are /G/few.
Where the rain never /Em/falls, and the /C/sun never /D/shines—
It's /G/dark as a /Em/dungeon, way /C/down /A/in /D/the /G/mine.
