Thanks for the help ... I have already talked to the Chief at the local band and he tells me the songs are "personal" and not for general distribution. They are pertinant to specific spirits, ceremonies and persons, so the are held in sacred trust and the concept of someone else using them is unconscionable. He did say, however, I could do it myself ... "fake it" as he put it. Such a cool dude. He also told me that many of the native songs recorded for things like 'wild west shows' and rodeos subsitute rude words for the traditional ones. Mostly aimed at making fun of whoever is using them. Sort of a perpetual joke at non-native's expense. Pretty funny when you think about it!
