Thank you very much for your help, it was very 
very, well, helpful!  It turns out that the song 
I was looking for is an unleased track... so now 
I HAVE to buy the box set in June and pray that 
it is on there.  Just in case anybody wanted to 
know, since thanks to revolutionarygirl I now 
know the name, the track I was looking for was 
African Rythym 2.  Thanks again
