Hello in this forum!

I hope someone can help me: I'm looking for a story of Charles Dickens. He writes about a group of laymen who play theatre, just for fun, for a public. This story is badly comic.
I read it before some years and I can't find it anymore, not in "London scenes", not in "Christmas stories", and I don't know where to look now.
I hope you have an idea? I would be very glad!
