Take a deep breath and dive underwater in the concert hall submarine with its musical crew, the BBC Concert Orchestra. Favourite CBeebies characters JoJo and Gran Gran are on board with a Gran Gran plan, and Andy has his submarine pod at the ready.

Join the crew to search for endangered creatures, find out fascinating facts, and collect sounds and pictures for your very own musical ocean scrap-book.

A magical multi-media event featuring CBeebies theme tunes, orchestral treats, live action film and animation and a few surprises along the way.

Multiple performance times.
