Lord Chamberlain's requirements

The Lord Chamberlain's requirements were a set of four prerequisites for a licence for a production in British theatres. These were printed in theatre programmes so the audience could be aware of them. The Lord Chamberlain's Office had control of theatres until 1968, including censorship of the production content as well as for logistical matters. In the 1980s, they were replaced by similar requirements applied by a local licensing authority.

The requirements cover:

1. Leaving the theatre at the end of the performance.
2. Freedom of gangways and passages from obstruction.
3. Limitations on standees.
4. Operation of the safety curtain during each performance.

Three of the requirements (leaving the theatre, freedom of the gangways and the operation of the safety curtain) were set to music by Flanders and Swann for the revue Fresh Airs and were later used as encores for their 'Hat' performances.
