I can tell you all that the students are not going to be able to memorize a John Denver song if they can't even get "Glory Colorado". Most of them probably don't even know who he is.
Just needs one of those things on the big screen with the lyrics and the bouncing ball like they have on Sesame Street. And with that, further simplify it to the only parts anyone knows anyway. Here's all you need to do:
Yada yada yada yada yada yada, yada yada yada yada yada
Yada yada yada yada yada yada, yada yada yada yada yada
Yada yada yada yada yada.
Yada yada yada yada yada yada, yada yada yada yada yada
Yada yada yada yada yada yada, yada yada yada yada yada
Yada yada yada yada yada.
And the Colorado Rocky Mountain high, I've seen it raining fire in the sky.
The shadows from the starlight are softer than a lullaby.
Rocky Mountain high, Colorado. Rocky Mountain high.
Yada yada yada yada yada yada, yada yada yada yada yada
Yada yada yada yada yada yada, yada yada yada yada yada
Yada yada yada yada yada.
Yada yada yada yada yada yada, yada yada yada yada yada
Yada yada yada yada yada yada, yada yada yada yada yada
Yada yada yada yada yada.
And the Colorado Rocky Mountain high, I've seen it raining fire in the sky.
You can talk to God and listen to the casual reply.
Rocky Mountain high, Colorado. Rocky Mountain high.
Yada yada yada yada yada yada, yada yada yada yada yada
Yada yada yada yada yada.
Yada yada yada yada yada yada, yada yada yada yada yada
Yada yada yada yada yada.
And the Colorado Rocky Mountain high, I've seen it raining fire in the sky.
I know he'd be a poor man if he never saw an eagle fly,
Rocky Mountain high, the Colorado Rocky Mountain high, I've seen it raining fire in the sky.
Friends around the campfire and everybody's high
Rocky Mountain high, Colorado. Rocky Mountain high.
Rocky Mountain high, Colorado. Rocky Mountain high.
