Coldplay have apologised to South American fans about the cost of tickets on their recent tour. Frontman Chris Martin said of the tickets: "We just found out how expensive they are and would like to say we are sorry. We didn't know beforehand. The tickets of course could not have been extremely cheap because we are playing smaller venues here, but the price is a little embarrassing. When you are a famous band, a lot of things happen that you don't know about".
Of course, if you profess to be the sort of socially aware do-gooder that Martin comes across as, one would think you'd make it your business to know.
