I said "con-man" because in order to do their work con artists typically must pretend to have emotions (i.e. deep concern for those they aim to bilk) that they don't actually have, and there was something about much of Morgan's "comeback" era playing that gave me that feeling -- in particular, that the overtly emotional gestures in his playing seemed to be just that, something separate from rather than the inevitable outgrowth of the musical flow. I should add, though I can't be wholly sure about this, that I think I had this feeling before rather than after after I became aware of the details of Morgan's criminal career.
I'm with Larry on this one.
