This is actually a song by a Philedelphia Hip Hop band it's like G-love or something, but anyway, it's a great cover, and he doesn't do much with it...

The progression is a simple

Dm, G, Bb, A
"Sweeping the floors open up the doors..."

and the chorus part goes,

Dm, A, Bb, G
"With the Rodeo clowns, they pick me up when i'm down, yah..."

They're all bar chords, and they're played like this...
     EADGBE
Dm - 557765
G  - 355433
Bb - 688766
A  - 577655


there you go...
Cheers,
Daryl
