WTF of the Day

Here's a video of a Holocaust survivor visiting various European concentration camps with his family, where they dance to the tune of Gloria Gaynor's "I Will Survive." First impression is rather against it, I think, as being in poor taste. But I will say this: how chuffed do you think the survivor was? If his life were mine I'd do something similar. What better way to throw a last, great "eat it" at the Nazis?
