Okay, this is an old thread, but I'm trying to put the songs I want to post where they belong, and the version I learned in Girl Scouts (Colorado, around 1968) is a little different. I think the last verse makes more sense, though.
A hundred and eighty were challenged by Travis to die,
By the line that he drew with his sword when the battle was nigh,
Let them that would fight to the death step over,
And them that would live better fly.
And over that line stepped a hundred and seventy nine.
Ai-yah! Santy Ana, we're killing your soldiers below,
So the rest of Texas will know,
and remember the Alamo.
Jim Bowie lay dying his powder was ready and dry;
From flat on his back, Bowie killed him a few in reply.
And young Davy Crockett was laughin' and smilin',
Old Betsy lay there by his side.
For freedom and Texas a man's more than willing to die.
The courier said of the battle, "It's bloody and loud."
The words of farewell in the letters he carried were proud.
"Fear not, little darlin', my dying, if Texas is sovereign and free,
We'll never surrender and ever shall liberty be.
