Jean Jenkins was an old school expatriate american ethnomusicologist who based herself in London and cruised all over the world recording sound and music in Africa, Asia and Europe until she died in 1990. Damn, she was older than my grandma!

This is a recording of hers - the "Cow Milking Song" (I gave it that name, actually it is "track 31".....cow milking is no job for a slouch.
Music from Ethiopia; Recordings by Jean Jenkins, [Topic 2001]
