Poznań Nightingales
The Poznańskie Słowiki (en: Poznań Nightingales fr: Rossignols de Poznan de: Posener Nachtigallen) is a leading Polish choir founded in 1939. When the Germans expelled the priest of Poznań Cathedral, Wacław Gieburowski (1878–1943), a choirboy Stefan Stuligrosz, then aged 19, took up running of choir in Gieburowski's name.
