Maybe you can help me: I'm looking for a song, name and artist both unknown, from Africa and featuring a very assertively-played acoustic guitar, a strong but non-piercing male vocal, and the word "Yangu", possibly in a call-response format with background vocals, easily recognized and frequently repeated. I heard it on a New Mexico NPR station quite a few years ago. I requested the playlist from the station, but the song wasn't on it; there was a song called Maisha Yangu by Joseph Mkwawa taken from the CD African Acoustic: Guitar Songs from Tanzania, Zambia & Zaire, but neither the song nor the artist was the one I was looking for. Thanks in advance.
