Wilton's Music Hall, Grace's Alley - East London.

Jim Linwood has added a photo to the pool:

Wilton's Music Hall is a grade II listed building, built as a music hall and now a more general-purpose performance space in Grace's Alley, off Cable Street in the London Borough of Tower Hamlets. It is one of very few surviving music halls in its original state.
