Boy, the mind is a terrible thing to lose! Singing it to myself I realize it is a variant of Ten Little Indians. What'll you have? sung like 'one-little, two-little'

OLD TIME FLAVOR! (a variant response, in place of Pabst Blue Ribbon) sung like 'three-little indians'

if memory serves thier gold medal was from 1893, so that would make it the World's Columbian Exposition in Chicago?
