I think the gig in Brussels was one of his biggest so far. (8000 people) But the concert was already sold out somwhere in july. And on ebay a tickets went up to 120 euros.
So I think that he also would sold out the sportpaleis (Antwerp)! (from 11000 up to 17000 people, it depends on how they build the podia, platforms...) Next year mika?
Ow or why not the koning boudewijn stadion? (Brussels, 50 000 people) ow now I am dreaming a bit too much
