HMS Pinafore – Summer 2019!

My Gallant Crew, Good Morning!

We are so so excited to announce our director for Pinafore. It was such a great year for applications and were in the fortunate position of having a really hard decision to make, but we’re delighted to announce Jessica Dalton as our director. She has fantastic ideas and a wealth of great experience, it’s going to be a fantastic show!

Rehearsals are well underway and we are having so much fun! The show will be performed from Wednesday 2nd June to Saturday 8th June at Bridewell Theatre, Blackfriars.

Tickets will be available soon from – keep checking back here for news of earlybird deals!
