Beginning in 1975 and through the 1980s, LOOM added American and continental operettas to its roster, eventually carrying over 30 shows in its repertory.

After this, she returned to continental operetta, playing Lady Babby in Edwardes's English language version of Franz Lehár's Zigeunerliebe (Gipsy Love, 1912) at Daly's Theatre.

When Edwardes found success, beginning in 1907, in mounting English-language versions of the new generation of continental European operettas to the London stage, Ross wrote the English lyrics for the adaptations, often with libretti by Basil Hood.

The company performs the entire Gilbert and Sullivan repertoire, as well as rarely performed American, British, and continental operettas, Edwardian musical comedies and other musical theatre, mostly of the late 19th and early 20th centuries.

It toured (although not continuously) and played London seasons of Gilbert and Sullivan operas and a few continental operettas, also issuing some popular recordings.

Still, Carte continued to produce continental operetta, touring in the summer of 1876 with a repertoire consisting of three English adaptations of French opera bouffe and two one-act English curtain raisers (Happy Hampstead and Trial by Jury).

The auditorium was rebuilt and, under Hollingshead, it became a venue primarily for musical burlesque, variety, continental operetta, including several operettas by Jacques Offenbach, and light comedy, under Hollingshead's management, from 1868 to 1886.

Since then, it has performed West End seasons and toured in the UK and internationally, offering a new repertoire of Gilbert and Sullivan, continental operettas and a few serious operas such as La bohème, often performed in the original languages.

According to Andrew Lamb in 150 Years of Popular Musical Theatre, "Schwarzwaldmädel represented all that was best in continental operetta."

John Hollingshead had managed the Gaiety Theatre from 1868 to 1886 as a venue for variety, continental operetta, light comedy, and numerous musical burlesques arranged by the theatre's music director, Wilhelm Meyer Lutz.
