I see no relation between do do, loulou, and doodle in the "Do let me go-Yeller Gels-Doodle Let me go" chantey and the Creole word dou dou. Nor does it, as far as I can see, have any relation to 'do do' in the Nevis Fête song referred to by Barry Finn; "St. Peter Down at Courland Bay" (Abrahams, pp. 29-31).

Hugill did not suggest any relationship, nor can I find any, thus I see little point in discussing a 'relationship' unless some evidence can be brought forward that one exists.
