Ico Ico is New Orleans "Mardi Gras Indian" song. not Zydeco. Local legend - Indian tribes took in runaway slaves and intermarried. New Orleans Blacks honor them each year by dressing in elaborate Indian costumes on Mardi Gras & St Joseph Day. The song is about the non-formal routes the different Tribes (Neighborhood groups or extended families) took as they walk the neighborhoods. Flag boys are the scouts looking for other "Tribes". When two tribes meet they have strutting contests. I like Professor Longhair or Neville Brothers version. Paul
