"It Is With Great Sadness And Regret That We Announce A Festival Called Wonder 2015 Has Been Cancelled.

It’s been a really tough decision to make, and one which we haven’t taken lightly, but we feel it’s the right decision. The festival was being organised by a team of four volunteers working around full time jobs, and it’s been difficult to give the project the time it deserves.

A really key part of the decision is that two of the organisers are expecting their first children quite soon. This is obviously excellent news in every way, but it’s made the financial risk involved in the festival a little too much. The festival was intended in part as a fundraiser for Sunday Assembly and had ticket sales been rocketing along, it would have been possible to continue but we felt the risk of making a loss was too high to continue.

We can’t thank everyone involved enough for their support and hard work. We still really believe in the festival and will have another crack next year but it just didn’t work out this time".
