Yep sorry - that was all Australian dollars.
Why do the tickets get higher? Simple - the show is larger. The Finns played at theatres - only needing to move a backdrop cloth and the sound system around. No rigging, no stage, no screens.
They had a small crew as well - less people to look after.
U2 would bring in a crew probably of over 100-150 people. So thats 100-150 flights, hotel rooms, meals and paycheques. Venue hire is not that cheap - its based on a reservation fee, a percentage of ticket sales and merchandise sales. That is big bucks. Add on top of that the price promoters have promised the act, the money the promoter wants to make on top of that and then the ticketing fees...
Now, 12,000 ticket buyers have to pay for all that. Factor in there will be 'dark' nights where there is no show - venues still need to be held as its stupid to move stuff in and out. U2 may do 4 nights in Sydney - note that wont be 4 nights n a row - this tour shows they are hesistant to do more then 3 nights in a row.
So empty venues still charge rental if your stuff is inside it!
Add freight charges for buses, trucks and internal flights. U2 probably wont fly the Vertigo jet here - thus they will hire a private plane in Australia. More $$$.
Smaller acts dont mind flying Qantas and Virgin Blue - but do you think Bono is up for a stint on a City Flyer? Uh, no.
The bigger the venue, the larger the show, the more stuff, the more people, the more cash.
Everyone is in the toruing business to make as much money as they can - as a lot acts dont see a cent of record sales as production and promotion eats into any possible profit or they dont get royalties for years after the fact. I heard that Guy Sebastian and Shannon Noll are just getting large royalty cheques now - two years after their debut albums came out...
Basically expect to pay out of the arse for U2. If Coldplay are charging $120 - and thats with a severely downsized show and taking a lesser guaranteed fee, U2 will charge a ton for the best seats.
