Despite his success in Paris with the French version, Thomas was asked to revise the work for the first performance at the Drury Lane Theatre in London on 5 July 1870. This version was given in Italian with recitatives (instead of spoken dialogue). The role of Mignon, originally for mezzo-soprano, was sung by a soprano (Christina Nilsson), and the role of Frédéric, originally a tenor, was sung by a contralto (Zelia Trebelli-Bettini). A second verse was added to Lothario's aria in the first act ("Fugitif et tremblant" in the French version), and in the second act, a rondo-gavotte for Frédéric ("Me voici dans son boudoir") was devised using the music of the "entr'acte" preceding that act, to satisfy Mme Trebelli-Bettini, who was discomfited by having to take on a role originally written for buffo tenor. Apparently the coloratura soprano Elisa Volpini, who was to sing Philine, felt that her aria at the end of the second act ("Je suis Titania") was insufficient, and another florid aria ("Alerte, alerte, Philine!") was inserted after the second act "entr'acte" and before Laerte's 6/8 Allegretto ("Rien ne vaut"). The finale was also much shortened. Philine's extra aria appears to have either never been orchestrated, or the orchestration was lost or destroyed. (Most sources say that the aria was performed and not cut from the Drury Lane production, implying that Thomas must have orchestrated it.) The aria is known from several piano-vocal scores and is included as an appendix, sung by Ruth Welting with flute and harpsichord accompaniment, as part of the 1978 recording with Marilyn Horne as Mignon. The recording also includes a second appendix with the original, longer version of the finale.
