My friend Marek saw yesterday’s post and sent me a YouTube video from the Krakow cabaret where Ewa Demarczyk sang in her early years. It contained great archival footage – not just of Demarczyk, but of dances and costumed parties with the youth and le tout-monde of Krakow – and watching I thought what a revelation it would be for Americans who grew up during the Cold War, with a vision of life behind the Iron Curtain as unremittingly bleak, and what a revelation it is today, not just during the pandemic, but in the age of social media, with its scenes of young people having absolute fun.
