Tarja and Marko are coming to my town, what songs can I expect from them?

I'm a huge Nightwish fan, and I mean Nightwish as a band, not particularly into the solo careers of their members/ex-members. Tarja and Marko are coming and I'm thinking about purchasing a ticket because you know, I like Nightwish and those two are basically Nightwish minus the name... I just don't know, what will they sing? Should I expect songs from their solo careers (of which I know none)? Or do they sing Nightwish songs? (Are they even allowed to?)

Just wondering what to expect from a Marko and Tarja concert in terms of actual songs. (I know it will be epic anyways but I like to actually sing along and I can't do that if I don't know what they are playing)
