Information given for each entry is as follows:

Title of production

Composer

Lyricist

Librettist and, where applicable, details of original work from which the musical’s book is adapted

London theatre or, where applicable, provincial theatre where work opened (some transfers are also noted)

Date of first performance in London

Dates of first performances in theatre clubs, provincial productions or outskirt London theatres which may have preceded the London opening are not necessarily included

PC = Principal cast members

MN = Main musical numbers

Where it has been possible to trace this information, all musical numbers are listed. The usual source for these lists is the original theatre programmes of the original production, and / or original scores where available. In a few cases, it has not been possible to trace a list of musical numbers from any source. Some programmes include misprinted titles, and in such cases the author has corrected any obvious errors. Titles of songs may also deviate from those by which they are generally known, but the original programme or score titles have been used in most cases. Changes in the list of musical numbers during the run are noted if known, but it has inevitably not always been possible to trace such changes.

Number of performances. Where there was no London run, this may read [Tour] or [Season].
