I always used to smile at his (very!) long name Jeri. His singing style is apparently 'isicathamiya', and they all sang in Zulu, with the clicks (love that)
Some people here in UK may remember the Heinz beans TV advert with the song 'The Star and the Wise Man' (Inkanyezi Nezazi)
Other songs I love include Diamonds on the Soles of Her Shoes, Homeless, and Rain, Rain, Beautiful Rain.
I'm sure Paul Simon is very sad too. He's exactly the same age, and they seemed to have been great friends.
