My Dad used to sing this song many years ago, usually after a pint or three.
The odd word or two might vary, but this is very close to the original
version.
I believe that it was recorded in the 1930s by Wilf Carter (aka Montana Slim)

Take My Boots Off When I Die

CHORUS : "Oh take my boots off when I die, when I die.
Take my boots off when I die.
When they hand me out my wings
I won't need those heavy things
So, take my boots off when I die."

"Oh! I've been a no-good cowboy, and I joined an outlaw band.
I shot my way from Texas down to the Rio Grande.
The ladies hearts were broken, and the banks were broken too
But now I'm through with all of that - my outlaw days are through."

CHORUS: "So take my boots off....etc."

"Well, I shot a guy in Dallas for beating up his wife.
The judge he took one look at me, and said "I'll give you life."
But it all turned out that the guy I shot was a wanted killer too.
Instead of life, I got his wife, and 15 kiddies too."

CHORUS: "Oh take my boots off....etc."

Hope that this is of some use to you.......Jim Long
