I guess I'm most familiar with this song from the Willie Nelson recording. For the record, here are the lyrics from arlo.net
Ridin' Down the Canyon
by Gene Autry and Smiley Burnett
When evening chores are over at the ranch house on the plains
And there's nothing left to do but lay around
I saddle up my pony and go riding down the trail
Just to watch the desert sun go down
CHORUS:
White faced cattle lowing, sagebrush everywhere
Granite spires are standing all around
I'll tell you folks it's heaven to go ridin' down the trail
Just to watch the desert sun go down
Ridin' down the canyon to watch the sun go down
A picture that no artist e'er could paint
Cactus plants are bloomin' on the mountain side
I hear a coyote calling to its mate
CHORUS
When evening chores are over at the ranch house on the plains
And there's nothing left to do but lay around
I saddle up my pony and go riding down the trail
Just to watch the desert sun go down
CHORUS

Ridin' Down the Canyon
by Gene Autry & Smiley Burnett
G B7 C G
When evening chores are over at our ranch house on the plain
A7 D D7
And all I've got to do is lay around
G B7 C G
I saddle up my pony and ride off down the trail
A A7 D D7 G
To watch the desert sun go down
G B7 C G
Ridin' down the canyon to watch the sun go down
A A7 D D7 G
A picture that no artist e'er could paint
G7 B7 G
White faced cattle lowin' on the mountain side
A A7 D D7
Hear a coyote whinin' for its mate
G7 C D G
Cactus plants are bloomin', sagebrush every where
A A7 D D7
Granite spires are standin' all around
G B7
I tell you folks it's heaven
C G
To be ridin' down the trail
A A7 D D7 G
When the desert sun goes down
