Input: Question: In what city did Henri perform Edmond Audran's Olivetter with Florence St. John's Opera Company? Passage:Henri first appeared on stage in 1879 at the age of 15 with Florence St. John's Opera Company, performing in Jacques Offenbach's Madame Favart at the Strand Theatre and Edmond Audran's Olivette at the Avenue Theatre, both in 1880, in the latter of which she played a small role. She appeared in other operettas with St. John but left in 1881 to help Lytton begin his acting career. They joined the company at Philharmonic Theatre, Islington in several plays, including The Obstinate Bretons and The Shaughraun by Dion Boucicault, and then, with Kate Santley, played at the Royalty Theatre. There they appeared in Ixion, or the Man at the Wheel by F. C. Burnand, but the theatre closed soon afterwards. Henri rejoined St. John's company, playing in Bucalossi's Les Manteaux Noirs at the Avenue Theatre in 1882. She then rejoined Santley's company at the Royalty in 1883 in The Merry Duchess, but Lytton was out of acting work all this time and was forced to take a variety of odd jobs. Henri then played in the lavish 1883 Christmas pantomime of Cinderella at the Theatre Royal, Drury Lane. Henri and Lytton married in early 1884, both aged 19, at St. Mary Abbot's Church, Kensington. Neither family attended the ceremony.
