A video of a Jewish family dancing at Auschwitz and other Holocaust memorial sites in Europe has received more than half a million hits on YouTube.
The film shows three generations of an Australian family dancing to the Gloria Gaynor song "I Will Survive" in front of the infamous rail tracks and "Arbeit Macht Frei" sign.
Artist, Jane Korman, filmed the video last summer on a trip to former concentration camps with her three children and her father, Adolek, who is 89 and a former prisoner at Auschwitz.
It has prompted fierce debate on YouTube, but most responses have been sympathetic from people who say they have been moved by it.
The BBC's Paul Henley spoke to father and daughter, Adolek Kohn and Jane Korman.
Was it a strange experience?
