complaining about the "strange idea" of adding a ballet, which he considered "a hideous blemish in that masterpiece", and he wondered why Bizet's wife had permitted it. At the Opéra-Comique, after its 1883 revival, Carmen was always presented in the dialogue version with minimal musical embellishments. By 1888, the year of the 50th anniversary of Bizet's birth, the opera had been performed there 330 times; by 1938, his centenary year, the total of performances at the theatre had reached 2,271. However, outside France the practice of using recitatives remained the norm for many years; the Carl Rosa Opera Company's 1947 London production, and Walter Felsenstein's 1949 staging at the Berlin Komische Oper, are among the first known instances in which the dialogue version was used other than in France. Neither of these innovations led to much change in practice; a similar experiment was tried at Covent Garden in 1953 but hurriedly withdrawn, and the first American production with spoken dialogue, in Colorado in 1953, met with a similar fate. Dean has commented on the dramatic distortions that arise from the suppression of the dialogue; the effect, he says, is that the action moves forward "in a series of jerks, rather instead of by smooth transition", and that most of the minor characters are substantially diminished. Only late in the 20th century did dialogue versions become common in opera houses outside France, but there is still no universally recognised full score. Fritz Oeser's 1964 edition is an attempt to fill this gap, but in Dean's view is unsatisfactory. Oeser reintroduces material removed by Bizet during the first rehearsals, and ignores many of the late changes and improvements that the composer made immediately before the first performance; he thus, according to Susan McClary, "inadvertently preserves as definitive an early draft of the opera". In the early 21st century new editions were prepared by Robert Didion and Richard Langham-Smith, published by Schott and Peters respectively. Each departs significantly from Bizet's vocal score of March 1875, published during his lifetime after he had personally corrected the proofs; Dean believes this vocal score should be the basis of any standard edition. Lesley Wright, a contemporary Bizet scholar, remarks that, unlike his compatriots Rameau and Debussy, Bizet has not been accorded a critical edition of his principal works; should this transpire, she says, "we might expect yet another scholar to attempt to refine the details of
