Yea Glen, that is about right before tax and costs, she pockets about 5-7 million a show.
When she did 52 concerts in Nth America she grossed 700 million and that is not counting the 50 other world tours.
It takes up to 100 Semi's, 4 cranes and about 150 crew to move it and set it all up and pull it down and each piece is loaded according to where it has to go, can you imagine it a bit went missing.
If she fly's overseas like to Australia it is not unusual to hire two Antonov Cargo Planes to move it all.
The logistics of it all must be enormous responsibility.
