Personnel apparently the same as on the Born Free set, which excerpts this entire performance of "Unity First."
Might as well share:
LB, Frederic Rabold, Herbert Joos, Michael Sell, Manfred Schoof - trumpets, flugelhorns
Albert Mangelsdorff, Paul Rutherford, Gunter Christmann - trombones
Joachim Kuhn, Dieter Scherf, Michael Thielepape - altos
JJ, Gerd Dudek, Heinz Sauer, Alfred Harth - tenors
RM - bass sax
Gunter Hampel - bass clarinet
Axel Hennies - flute, piccolo, tenor sax
Gerhard Koenig - guitar
MF, Peter Stock, Claus Buehler - contrabasses
Rainer Grimm - percussion
Jeanne Lee, Karen Krog - vocals
Including the intro by Bowie, it's about 37 minutes.
It's good. PM me if you want a copy.
