The venue is brilliant, an elegantly designed marquee built from steel, cotton and canvas on the shore of Lake Toolonlahti in central Helsinki. It even comes with a sloping floor so that everyone can see the main attraction, German-born DJ/gypsy music advocate Shantel. His Orkrestra are hugely entertaining, and while the lyrics might appear trite to those of more "sophisticated" taste ("yabadabaday yoboboboboy, I wanna be your disco boy"), there's more fun here than a lifetime of bouncy castles will provide. False endings are de rigour, crowd participation is compulsory (at one point he has the entire audience kneeling on the floor before the arena erupts into a rousing version of the Italian partisan anthem "Bella Ciao"), and while the show might not be as authentically Romani as some you'll see, it's no less exhilarating.
