Adolek Kohn is the old man dancing in the first video.
Him and his grandchildren are dancing to the Gloria Gaynor song "I will Survive".
They are dancing at the gates to Birkenau, Aushwitz, and other concentration camps in Poland.
He is a survivor of the camps, and IMHO has every right to be dancing in front of them.
Some people think its disrespectful, but to me its a celebration of life.
I say more power to him!!!
The 3rd video is him taking his grandchildren inside one of the cattle cars used, with him roleplaying for his grandkids what it was like.
