PG-Nelly Furtado is sort of like Lucinda Williams with a dance beat. Anyway, you are right about yodeling--that is almost exactly what it is--somewhere or other, we had a thread where we talked about the Hawaiian roots of yodeling in country and popular music--Yodeling/falsetto singing of exactly the type we are talking about here is a part of traditional Hawaiian singing--Rose Moe, with her family, in Mme Riviere's Hawaiian, preserved the old singing style in a number of recordings made in the 20's and 30's, and continued to perform in that style for many years--My understanding is that the technique was actually taught in the Hawaiian music school, though I don't know any more about it than that--
