Artist: Pete Seeger
Song Title: Camptown Races
Well, I came down there with my hat caved in
Oh I'll go back home with my pocket full of tin oh doo-dah day
Goin' to run all night, goin' to run all day
I'll bet my money on the bobtail nag, somebody bet on the bay.

Well, the Camp town ladies sing this song doodah doodah
Ah the Camp town race track's five miles long oh doo-dah day
Goin' to run all night, goin' to run all day
I'll bet my money on the bobtail nag, somebody bet on the bay.
