Remember that 70s hit by Toto, Africa? I remember it really well because my sister and her husband played it a lot when I was little. Anyway, a different dear brother-in-law (my husband's brother) put me onto this Youtube clip of a choir doing this song.
Check it out and let me know what you think. I really love the Michael Wislow/Jerry Seinfield guy! (I think I secretly wish I could do mouth percussion).
