Following the success of Chefs-d’oeuvres de l’opéra lyrique (1941) and Hősszerelmesek (1943), Emlékezetes Operettek (Memorable Operettas) was a natural sequel. Operetta was immensely popular in interwar Budapest, having thrown off the oppressive traditionalism and seriousness of the Habsburg period. After becoming independent from Vienna, the Hungarian capital was able to become an autonomous centre of international entertainment as important as Berlin and New York. The range of operetta theatres was expanded by the establishment of the Revue Theater (Revü Színház), which also had a summer theatre (Scala Theater), and later as the Blaha Lujza. In 1922 the Capital Operetta Theater (Fővárosi Operettszínház) was established, which also had a secondary theatre under the name Summer Operetta Theater (Nyári Operettszínház).

The range of operettas which were regularly performed included imports from Vienna, Berlin and London, but the most popular were the Hungarian classics – Bob herceg (Prince Bob) by Jenő Huszka, first performed at the the Budapest Folk Theatre in 1902, and János vitéz (John the Valiant) by Pongrác Kacsóh, first performed in the Budapest Király Theatre in 1904.

Székely would have been very familiar with the popular productions of the period, and produced this very typically Székely portfolio of in-your-face sexualised versions of all the standard operettas.
