The fragment is a reference to one of the most curious groups in the history of Polish theatre – namely, the theatrical revue unit embedded in Anders' Army. Accompanying the military unit on a route spanning from the USSR through the Middle East to Italy, Oleńska – who was part of the ensemble Polish Parade (Polska Parada) – created a persona called Helenka, who appeared in a song by the composer Henryk Wars.
After the war ended, Oleńska appeared in the Polish-Italian movie Wielka Droga (The Great Road, trans. NS), starring Irena Anders (listed in the cast under her stage name Renata Bogdańska) in one of the main roles. In the film, Oleńska performed the tango song Gdzie Najlepiej with music by Henryk Wars and lyrics by Aleksander Świtaj, a nostalgic piece about the city of Lviv.
Oleńska and her husband were active organisers of the émigré Polish community in London. She performed in the productions of Polish Stage Artists' Association Theatre, appearing in shows based on the work of Julian Tuwim and Zofia Kossak-Szczucka. In 1965, the couple was invited to Chicago by Ref-Ren's cousin, Feliks Konarski, where Oleńska lived until her death in 1983. She is buried in a military grave in the Catholic Maryhill Cemetery in Illinois. Eight years later, her husband was interred next to her. Oleńska was decorated with the Monte Cassino Commemorative Cross.
