Here's a song I listened to over and over as a kid--yeah, I totally recognized this 45!--and even though I had no idea what it was about, I still remember all the lyrics. Songs are weird that way. They seem to stay in your head a LOOOONG time. What brought it to mind was I just finished watched 'The Hangover' and it was on the soundtrack.
Anyway, I read this about the song from it's author: "It came from two Indian chants that I put music to. “Iko Iko” was like a victory chant that the Indians would shout. “Jock-A-Mo” was a chant that was called when the Indians went into battle." Don't know if it's true or not.
