Barry, couldn't resist looking up more info on the "Bad Girl". I found more than I have the time to post here. It is derived from "The Sailor Cut Down in His Prime." The family of ballads with the guilt-ridden moral that Love Kills... Other titles in the family include, "The Unfortunate Rake", "The Irish Rake", "The Unfortunate Lad", "The Rakish Young Fellow", "St. James Hospital", and "The Rambling Boy". Syphilis often did them in:

Had she but told me before she disordered me
Had she but told me of it in time,
I might have got salts and pills of white mercury,
But now I'm cut down in the height of my prime.

The bad girl versions include "One Morning in May" and "The Young Girl Cut Down in Her Prime". There is that "wrapped in white linen and cold as the clay" fate that later befalls our American cowboy. There are also versions for a lumberjack and a miner dying of silicosis, which comes close to home here.

Twas once in the saddle I used to go dashing,
Twas once as a cowboy I used to be brave,
But ain't it a pity I came to Butte City,
To work for Jim Brennan, and now to my grave.

Alice in Montana (but not in Butte)
