On German radio station Jump (and I think also on NDR 2 at least I heard an announcement of contest for winning tix incl. Bon Jovi) they have a contest where you can win tix for a promo concert in Amsterdam. Jump couldn't/didn't want to give any further detail like when exactly it will be and if there also will be tix for sale though.

A few people heard it on the radio today and talked to Jump Radio.
