Rev Alan Smylie: the play is immoral

"The very fact that it is adults only indicates what the content is.

"We're here standing for standards that have been forsaken, moral standards in society, decency.

"We feel that those who produce these type of productions have a responsibility to the general public.

Rev Smylie said that even though he had not seen the play, he was still in a position to judge.

"I don't think you have to drink poison to know it's poison."

Needless fuss

Director of the opera house Derek Nicholls said the play was merely harmless comedy.

"Everybody is entitled to their opinion, so if the protestors have a particular view that's fine.

"But equally the freedom of the people who've come to see the play should be respected.

He said there was no indecency on stage.

"We see torsos, but absolutely no nudity.

"I think you get the same picture if you go to the swimming baths every day really, so I don't understand the problem."
