I actually know little about Doro, and from what I've been youtubing, it's a lot of hit or miss for me. Seems like it could be a fun performance though and cool to get the opportunity to suddenly see her.
Sucks Ben, you may still be able to sell the tickets though, for day 3 and 4 id think for sure? It's right around the corner so thats a pain though to have to suddenly figure this shit out.
