The Lyrics, as sung by the Aggie Band-Uh:
He always sings
Lazy music to his cattle as he swings
Back and forward in his saddle on a horse
(pretty good horse)
That is syncopated gaited
There is such a funny meter
To the roar of his repeater
How they run
When he shoots his gun
Because the western folks all know
He's a high-falootin' rootin' tootin'
Son of a gun from California
He's some cowboy
Talk about you're cowboy
Ragtime Cowboy Joe!
