This interdisciplinary study attempts to make sense of what has long been regarded as a chaotic period in the history of opera in London. In 1778 R. B. Sheridan acquired the King's Theatre and its resident opera company in what we would now call a leveraged buy-out, plunging the opera into escalating debts that were to haunt it into the 1840s. The 1780s and early 1790s were a stormy but exciting era: the company hired some of the foremost singers and dancers in
Europe; ballet d'action came to London, with Noverre himself as ballet master; the company employed such composers as Sacchini, Anfossi, Cherubini and ultimately Haydn; it went bankrupt and carried on through years of wrangling in Canchery; the King's Theatre burned down in 1789 and was rebuilt and
re-opened in defiance of the Lord Chamberlain's refusal to license the new building. Drawing on librettos and scores, ballet scenarios, pamphlets, scattered manuscripts, legal records, architectural drawings, newspapers and other sources, the authors reconstruct the history of the company its shifting artistic policies, analysing opera and ballet repertoy, performers, production circumstances, finances and managerial infighting.

Following on from the volume on the King's Theatre, Haymarket (published by OUP in 1995), this interdisciplinary study of opera and ballet now turns to London's Pantheon Opera during the period 1789-98. The discovery of six cartons of previously unknown manuscripts in the possession of the Duke of Bedford makes possible the rewriting of a hitherto dark and little understood chapter in the history of opera in London. The King's Theatre, Haymarket, burnt down in 1789.
To replace it, the fifth Duke of Bedford and the Marquis of Salisbury secretly backed a new opera company, to be housed in the Pantheon, an elegant exhibition hall hastily converted to house the venture.

Part 1 of this book tells a tale of intrigue, blackmail, bankruptcy, arson, and high-society infighting against a background of exalted artistic aspirations and genuine love of opera. The Pantheon tried to engage Mozart to compete against Haydn, and hired some of the most notable singers and dancers in Europe. Mismanagement led to huge losses, and the theatre burnt in highly suspicious circumstances in 1792. The backers tried to impose an artistic vision and financial controls on the management
of the rebuilt King's Theatre, Haymarket, when opera returned there in 1793, but by 1795 their failure was evident.

The second part of the book is a detailed analysis of the opera and ballet repertoire, personnel, management, costumes, staging practices, and finances of the company, based on the Bedford archive and a wealth of hitherto unused sources. What emerges is the fullest operational analysis ever published of any pre-nineteenth-century English theatre or opera company.
