I don't think he is making that claim but he definitely likes to make a lot of noise around himself.
These kinds of endeavors are team efforts, seems obvious to me. He definitely is not what I would call a 'team player'. Lots of take and no give.
If he was precluded from doing the favor in return that I asked for, I could have understood. But acting like he did not understand what I was asking for was just insulting my intelligence. There was no way he could not be in possession of the information I was asking for, he could not have done what he wanted to do without it.
I used to be in awe and even lined up a lecture for him at the DC Jazz Archives to talk about his work. But I had to walk away. His loss, anyone who works with me know I am meticulous. I could be an asset to anyone who is not trying to treat me like 'the help'.
I am involved in a new project which had some initial bumps, but I think now they have figured out what an asset I can be.
