Hi Ingrid,
A friend of mine most likely will go to only one of the three Amsterdam shows although he has tickets for all three of the shows. Actually I bought the tickets for him on mk.com, so I'll have to get the tickets before the show (hopefully before the doors open...). So I may able to provide you with one ticket (don't know exactly which date; I'll have to contact my friend). Send me an e-mail for details.
