I'm taking advantage of Eurostar's 'any station in Belgium' ticket to go and see this (I'm pretty sure that's not what the ticket was designed for as I shall be using it to go to Welkenraedt and then hopping over the border to Aachen, so very little of my budget will actually be spent in Belgium!).
I've booked for 2 Nov but it seems I and anyone else who's interested can watch the opening night's performance live online on Sunday. Details here:
http://www.theater-aachen.de/I'm not sure I should avail myself of this opportunity but I thought I should mention it here for the benefit of anyone who might want to watch. I was a little disappointed to find that
Die Dreigroschenoper is sold out for the night before but I'm ever-hopeful that returns will become available.
