....my lucky brother got paid to be there. He does sound (or something audio-related, can you tell I have no clue what he does for a living but it's something to do with electronics and computers??) at Suncorp Stadium in Brisbane so he was being paid to sit there and listen to them.
Most of what he does is boring soccer games (that few people turn up to), rugby league (I'm slightly more interested in those) and other sporting events. But the stadium can host up to four other big major events or concerts per year. Coldplay would have been pretty good I think.
