Or more properly, The "Texas" Rangers sing Cheyenne. These Rangers, you see, hail from somewhere in Great Britain. This song appears on a British EP with three other TV Western themes. How do I know the group is actually British? The accents. They're barely noticeable on this track, I admit, but come through loud and clear on their version of "Wyatt Earp" (coming soon).
