Here is what I got, lyrics but not chords to "Denver".
John Denver got his stage name from this song, I believe.
I tried to transcribe the lyrics to "Ramblin'" and "A Travelin' Man" as well, but failed. A few words I couldn't recognize clearly.

DENVER
(Randy Sparks)

Ha!
Come on, big mule!

I was drivin' a rig outta Texas
All loaded an' bound for Cheyenne
Takin' my pleasures so freely
Just a good lovin' ramblin' man

I had quite a way with the ladies
"Sweet Daddy" was my middle name
Till I got to a place they called Denver
And I ain't never been quite the same
Ha!

I've been to St Louis and Abilene
I've rambled through many a town
But I got me a woman in Denver, Lord
That's where I'm settlin' down

Well, I kissed her an' swore that I loved her
I told her some day she'd be mine
And then I laughed all the way back to Texas
Hah-hah, to think she'd believe that ol' line

Well, I got to pinin' for Denver
It's funny how things come to be
As I slipped the ring on her finger
Well, I knew that the laugh was on me
Ha!

I've been to St Louis and Abilene
I've rambled through many a town
But I got me a woman in Denver, Lord
That's where I'm settlin' down

Now all you young fellas take warnin'
You single men, run for your life
Be careful an' stay outta Denver
Or else you'll wind up with a wife

You'll walk down the street unsuspectin'
And you won't believe what you see
'Cause the prettiest gals live in Denver
Lord, you'll wind up happy like me
Ha!

I've been to St Louis and Abilene
I've rambled through many a town
But I got me a woman in Denver, Lord
That's where I'm settlin' down

Come on, big mule!

Got me a woman in Denver, Lord
That's where I'm settlin' down
Ha!
