Hey guys, have just got back from a long weekend in Amsterdam to celebrate a mate turning 40, had a blast

Was strolling around the city centre yesterday, when I hear a guy in Dam square, being quite aggressive on a hands free microphone, he has an audience of around 50-65 people in a semi-circle and is all "come on guys, for f*** sake, its not complicated, move closer, move towards the rope" (he has a rope set up to form a semi-circle), "come the f*** on guys, its not f***ing complex, the quicker we all move closer the quicker I start the magic" - I go and stand and have a look. He is promising to finish the show with an escape from a straight jacket and 30 foot of chain around him.
It all of a sudden became very compelling viewing, as he set about abusing most of the people walking by
"get your hands out of your pocket, we know what you're doing"
"did you know one in three guys in Amsterdam is gay (as he turns to three guys) HI GUYS!"
Turning to two old guys..."hey you two, how are you? When did you get back together?"
And this goes on and on! I actually found it amusing, maybe slightly on the aggressive side but he kept the crowd for an hour! At the end in his straight jacket and chains he asks people for either 10 Euros or 5 Euros if they can't afford that, ballsy I thought as most people would just be tempted to chuck some change in imo. In the hour I saw, and I found out afterwards this was pretty much the whole show, he did 3 tricks, a cigarette vanish, a bill change, and the escape finale.
Afterwards I went for a beer with him, and he counted his money up, just over 250 Euros, not bad for an hours work, and a quite unique style! He came across as a nice guy, showed me a couple of things with cards and coins that were pretty good as well
Anyone seen this guy perform? Anyone know him in fact? Mark Cmor if memory serves...
