Will BM and RT attend showcase Dutch WWRY?

So what do you guys reckon: will either Brian or Roger show up at the showcase of the Dutch WWRY this Tuesday in Amsterdam? Not necessarily on stage of course, but just to check it out maybe?

I sure hope so, I got in so!
What will it be like, will they play the whole show or just a part and will BM attend there?
