Waitin' for the bus all day

"Have mercy, been waitin' for the bus all day.
Have mercy, been waitin' for the bus all day.
I got my brown paper bag and my take-home pay.

...

Right on, that bus done got me back.
Right on, that bus done got me back.
Well, I'll be ridin' on the bus till I Cadillac"

Music And Lyrics by Billy Gibbons & Dusty Hill
