Cecilia Motley, Shropshire Council’s cabinet member for communities, culture, leisure and tourism, and transport, said: “We are delighted the panto cast and our team at Theatre Severn have enjoyed a successful run.

“Our thanks go to everyone involved and also to the audiences who did their bit to make the production safe and successful.”
David Jack, Shropshire Council’s theatre services manager, added: “It has been wonderful to see panto back on stage, and entertaining audiences of all ages once again.

“We’re so grateful to everyone involved and thank our audiences for their special part in another hugely successful panto season.”
