Here's the lyrics:

Jackie O went ridin'
To the Wounded Knee...
Jackie O was killed
In the battle in 73...
- I was his last friend
And I watched him die...
As the angel grabbed him
- I said: Fly Jackie fly!

Jackie went from pain and misery
To join the warriors
Down at Wounded Knee

I watched the dying Jackie
Untill the morning broke
The distant thunder faded
Of the blue-shirts second stroke...

I knew the fight was over
And we had lost again
Both here and in South Dakota
Where I had lost a friend!!.

Jackie went from pain and misery
To Join the warriors
Down at Wounded Knee
