"please tell us all how much of $1.2 million she'd be left with once all the costs are paid"
About $190,000, according to Amanda Palmer. Is she somebody in the music industry that you know who she is?
Of course, Palmer didn't include the gate money from the tour in her estimate, which should pay for all tour costs - that's how it works. So that $190k is by her own admission clear profit for her.
