They knew each other at school, but they weren't great friends. Tuomas' mother used to teach Tarja piano & that's how they knew one another. As she was one of the few girls in the school, her singing efforts were always encouraged, hence why Tuomas remembered her for when he wanted his own band with female vocals.
But I guess towards the end their relationship was dwindling, Tarja had to finish her studies (she got properly trained in classical singing) & I guess she needed to spend time with her husband too. *shrugs shoulders* from what I know I guess other factors were driving them apart.

Thanks, She_Is_My_Sin !!! :)

That's ok. Gosh, I've read too many Nightwish interviews.

I like Nigtwish but I haven't heard that many of their songs to name one as my favourite. I love Tarja's voice its a pity she isn't with them any more.

I do enjoy them very much, but they're one of those oh so common cases of a band being destroyed by their annoying fan base.
