One more thing...
Between 1985 and 1988 I chased Michael Brecker a lot: I wanted him to do a 3 day project in my school. On a rainy day in April 1987, he eventually let me into his appartment on Grand Street, New York and agreed to the project.
I left countless faxes and messages on his answering machine but no replies, no contract...
My last desperate message: "Listen Mike, I the umbrella behind your couch is mine: an excellent Dutch HEMA-umbrella. You can keep the umbrella but I need the contract".
The next day the signed contract came in.
'The Michael Brecker Artist in Residence Porject 1988' in The Hague, The Netherlands, was a great success.
