He and Kazimierz Krukowski performed as the duo Lopek and Florek in kleynkunst productions at Qui Pro Quo and other noted Warsaw cabarets.

He returned to Warsaw after the war, but no theatre would hire him and he spent several years giving dance lessons and occasionally singing in cabarets.

His debut came in 1925, when he was hired by the famous Qui Pro Quo cabaret as a singer and dancer,[4] "immediately conquering the audience with his natural juvenile wit and temperamental performances of Warsaw street types.

"[1] He remained part of Qui Pro Quo's crew until 1931, appearing on stage along such stars of contemporary Polish cabaret and cinema as Marian Hemar, Eugeniusz Bodo, Hanka Ordonówna, Mieczysław Fogg, Mira Zimińska, Zula Pogorzelska and Fryderyk Jarosy.

Perhaps, need to laugh again was strong enough in the society so deeply traumatised by the atrocities of war, and Dymsza's talent in evoking happy-go-lucky air of the past Warsaw street was highly desirable.
