Late 19th century traditonal American cowboy song.
Now old Dunny was an outlaw, he'd grown so awful wild He could paw the moon down, he could jump a mile; Old Dunny stood right still there, like as he didn't know Till the stranger had him saddled and ready for to go. When the stranger hit the saddle, then old Dun he quit the earth, And started travelin' upwards for all that he was worth, A-yellin' and a-squealin' and a-having wall-eyed fits His front feet perpendicular, his hind feet in the bits.
