Laibach prizes till Sunday March 08, 2015 21:00 (UTC+01:00)

In my Thursday show I started first games for my listeners with the prizes directly from Laibach's camp. The end of the competitions has been set on Saturday March 08, 2015 21:00 (UTC+01:00), after the show replay (Sunday 17:00 UTC+01:00)
What the prizes are? 3 special invitations from the band for Kontrapunkt listeners for Laibach gig in Krakow, Club Fabryka March 25, 2015 and 2 T-shirts - one girlie and one male both M size (both with the certificate of genuineness).
If you want to be one of the happy winners you only need to answer one simple question and send it to me using contact form on Rock Serwis FM kontrapunkt page. Unfortunately prizes are only for those who can collect them from the house of Rock Serwis FM located in Kraków - no shipments this time sorry.
Question is - when did Laibach visit Kraków for the last time? Please give the exact day date.
