seems like you've got a pretty good handle of the people i've had the oppurtunity to watch and try to learn from being yourself and communicating that with the audience and gaining their acceptance of that a lot of folks have acts that they regularly do(which is fine ) as long as they beleive in them enough to get the people beleiving it too i've found it tricky at times a true performer the likes of ray wylie hubbard they are few and far between but hubbard was always one of the finest bullshit artist irt has been my good fortune to have known from way back in the begining i'm sure that performing can be taught but some are just born with a natural affinity for it i'm not quite that fortunate (i have to struggle for what i can get of it)
