Here're the lyrics I posted to the old thread:

It starts out with a typically first 2 verses, then:

At Talequah on the reservation
Far away you rolling river
I joined General Pike and the Cherokee Nation
Away I'm bound away
Across the wide Missouri

The Yankees came to Elkhorn Tavern
Far away you rolling river
The Southern hopes and nations shattered
Away I'm bound away
Across the wide Missouri

Oh Shenandoah I love your daughter
Far away you rolling river
The Cimmeron and Red Fork waters
Away I'm bound away
Across the wide Missouri
