He returned to Poland and first worked as an organist in St. Trinity Church, while also playing piano in nightclubs.
Kataszek composed dozens of Polish foxtrots, black-bottoms, shimmies, and Charlestons often performed at the small night spots of Warsaw: Qui Pro Quo, Perskie Oko, and Rex - they included A ile mi dasz?
In 1933 he and Karasiński wrote two "schlagers" (hits) for the comedy film Każdemu wolno kochać: the rumba Chcesz to mnie bierz" (Take Me, If You Feel Like It) and the Każdemu wolno kochać (Everybody Has A Right To Love).
When deportations to Treblinka and Bełżec started, he escaped to the "Aryan" side of the wall and went back to Lviv.
He went back to bandleading but was recognised by an SS officer, arrested, sent to Pawiak prison in the Warsaw Ghetto, and shot on 22 May 1943.
