CAMPTOWN RACES
(Stephen Foster)

De Campptown ladies sing this somg,
Doo-da, Doo-da
De Camptown racetrack's two miles long
Oh, de doo-da day

cho: Gwine to run all night
Gwine to run all day
I bet my money on a bob-tailed nag
Somebody bet on the gray.

Oh, de long tailed filly and de big black horse,
Doo-da, doo-da@00-da,
Come to a mud hole and dey all cut across,
Oh, de doo-da day.

I wnt down South with my hat caved in,
I came back North with a pocket full of tin.
