The Yeomen of the Guard is one of the most popular and enduring Gilbert and Sullivan Savoy operas. This critical performing edition, edited by Colin Jagger, Director of Music, University of Portsmouth, marks the 125th anniversary of the opera's first performance. The edition presents the opera as it was originally conceived, correcting errors found in older editions (regarding music, dialogue, and stage directions) and including unpublished songs and alternative endings. The vocal score is clear and practical as well as scholarly and authoritative, reflecting the editor's experience as a conductor. Full scores and clearly printed orchestral parts are available on hire/rental, and are consistent with the vocal score. The full score is also available on sale. In a further break with other editions, the vocal score includes the complete libretto.
