Um, WHAT is with all the fighting in this thread?
Britney and J.Lo both sold 100% capacity of their respective shows. Thats 100% of asses in 100% of seats. THAT'S the part you guys should be reading. Any differences in overall gross is merely difference in price and capacity arrangements. It has no impact on demand.
Seriously, do you guys even bother to apply logic and reason to your arguments or do you just see numbers at face value and spazz out?
