[Verse 1]
There's a rainbow on the Rio Colorado
There's a haze around the western Texas moon
Someone waits beside the Rio Colorado
'Cause I promised to come back to Texas soon

[Verse 2]
When the dawn comes breaking through
This lonesome buckaroo
Will be riding down a trail I used to roam
There's a rainbow on the Rio Colorado
And it calls me to my western Texas home

[Verse 3]
When the dawn comes breaking through
This lonesome buckaroo
Will be riding down a trail I used to roam
There's a rainbow on the Rio Colorado
And it calls me to my western Texas home

[Outro]
Yes it calls me to my western Texas home
