"Custer's Blues" lyrics - THE WATERBOYS

Well you look just like General Custer
On the day of his last stand
Heading up proud and glorious
Singing "this land is my land"
Sword it by your side
And map in your hand
Heading up into the rain
Singing "this land is my land"

Now I've seen your dust arising
Lord, your horses smell
I've seen you crossing across the bad lands
And I've seen you towing your line as well
I've watched you when you're sleeping
I've seen you filling up your can
Singing as you work
That this land is my land

You're busting into my country
Messing up my fields
Playing games in my holy places
Tearing the earth with your wheels
Right now your star is ascending
And your head is busting with pride
But I wonder if Custer was still singing
"This land is my land" when he died

Was he still singing "It's is my land" when he died?
Was he singing when he died?
