The goose in London was not featherweight. That animal was not having it and attacking the actor during its star scene. I would be tempted to return the anger but my stance is that real animals should not be on stage at all. They have free will and being paraded before an audience may not be their aspiration in life.
I'm going to see the replacement cast on Friday. I thought it was a good play but the writing was pure fantasy pertaining to be somewhat factual. There was some controversy as Butters does not know anything about it.
The performances over all were excellent in London. My Todaytix 15 pound ticket in center stalls was a strong selling point as well.
