It could possibly come from this radio broadcast, which I have had in my collection for a couple of years now.
Osborne, Mike 10/17/80 3. Kölner Jazzhaus Festival, Musikhochschule, Cologne, Germany
Mike Osborne (as), Dave Holdsworth (tp), Marcio Mattos (b), Brian Abrahams (d)
It is in deed very good and I will be sure to purchase it once it is officially released. To me, Osborne occupies a similar space as Jimmy Lyons in some ways and I have really enjoyed his playing since a friend hipped me to him.
That's it.
FMR I've heard conflicting reports about. No they're not anything to do with Ogun...
