The version I learned were like this

I'm an old cowhand from the Rio Grande
But my legs ain't bowed and my cheeks ain't tanned
I'm a cowboy who never saw a cow
Never roped a steer for I don't know how
And I sure ain't fixing to start right now
Yippi Io Ki Ya Yippi Io Ki Ya

Im an old cowhand from the Rio Grande
And I learned to ride before I learned to stand
I'm a riding fool who is up to date
I know every trail in the Lone Star State
Cause I ride the range in a Ford V 8
Yippi Io Ki Ya Yippi Io Ki Ya

I'm an old cowhand from the Rio Grande
And I come to town just to hear the band
I know all the songs that the cowboys know
Bout the big corral where the doggies go
Cause I learned them all on the radio
Yippi Io Ki Ya Yippi Io Ki Ya

I'm an old cowhand from the Rio Grande
Where the west is wild around the border land
Where the buffalo roam aroud the zoo
And the indians make you a rug or two
And the Old Bar X is a barbecue
Yippi Io Ki Ya Yippi Io Ki Ya
