(Little ). The youngest of “Three sailors of Bristol city,” who “took a boat and went to sea.”
There was gorging Jack, and guzzling Jimmy, And the youngest- he was little Billee, Now, when they got as far as the equator, They had nothing left but one split pea. To gorging Jack says guzzling Jimmy, `We've nothing left, we must eat we.'
[They decide to eat Little Billee, but he contrives to escape.]
