As far as I can tell, Hedwig did not sell well in Boston, and I'm not entirely sure why. As has already been mentioned, there was very little press and advertising. I have found both Hedwig and the Boch Center's social media adeptness to be lacking.
The show was not marketed well and, if you ask me, the tickets were overpriced.
With that said, I found Euan to be tremendous and the show tours well.
SDV: I didn't mean to imply that all one needs to portray Hedwig successfully is charisma and a nice voice.
What I intended to say was that, with stage presence and a great voice, Hedwig (the show, not the woman) will never be an entirely unsalvageable experience. Those two attributes will generally be enough sugar to help the medicine go down and sell the show to the general theatergoing public.
