Thanks. It was Arlo Guthrie (and previously, it was done by a [white!] South African outfit called "Wait a Minim", who made a small name for itself in the '60s by recording chants and songs of various native peoples long before "world music" became a phrase. It's interesting because on of their various drummers, Nigel Pegram, went on to become the drummer for Steeleye Span. Small world...!)
