In reply to comment above, people can get tickets (£12.50 - under 15's £7) from Oxfam in Hessle Square, who have offered to be a local over the counter ticket outlet for this one. In return, they are making an additional £1 per ticket bkg fee to go to their fundraising, which seems fair enough.

Otherwise, if Hessle isn't handy or you want to avoid bkg fees, phone 01274-588614 or 07809-157845.
