Today John Van Der Put, aka Piff The Magic Dragon, posted this video on YouTube. It's an excellent rebuff to the man who stole Van Der Put's act.
I am told that the woman in the video who criticises the imitator looks like Kate Medvedeva, an accomplished magician, and so recognised the act as being an imitation. Facebook, Twitter, YouTube and other sites contain a huge number of supportive comments and messages for Van Der Put, as well as a great deal of condemnation for Chekanyuk.
