Four solo albums (seven if The Cross counts as well) + a couple of singles (Testify, Manipulator, In Charge Of My Heart, Unblinking Eye).
You have nearly 80 / 90 songs there. Yet, at the time to make up a set list, Roger keeps ignoring his solo discography and play some covers and the usual poppy songs instead. A real shame.
Plus, he plays Fat Bottomed Girls for an audience of non-Queen fans and nothing "new" for the hardcore ones.
