I've seen
Piazza three times- all with different Fabrizios.
The first time I saw it, first performance after the Tony Awards, Fabrizio was David Burnham- he was splendid. Second time was a few weeks before Matthew Morrison left- he is indeed talented. Third time was with Aaron Lazar, a couple of weeks after he assumed the role- he was impressive.
The point? Of all the three Fabrizios I've seen, I find David Burnham to be the most stunning- then Aaron, then Matthew. And that doesn't Matthew was the worst or what. It just depended on the day I saw them or something.
And I haven't seen
Piazza in a while- I'd love to see it again.
