I'm quite surprised at the lack of Nightwish songs. That's what she's best known for. Also, usually when a lead singer of a band does a solo tour, they always do songs from the band they were in. Bruce always did some Maiden songs and Ozzy always did some Sabbath songs and so on. Tarja still would be great to see regardless though.
