Sent me Mum to this for Xmas, her summary is below, but no surprises with the reception to Journey, they are virtually unknown in NZ! Ma only knows them because of me (but to be fair I know Deep Purple becuase of her, so we're even!):

Well the Purps were amazing, you would have been very happy to be that close to Steve Morse (as I was).
Not sure about the crowd, think they were mostly there for Deep Purple, and didn’t give Journey a very good reception – just sat in their seats mostly, but Journey was very good, and the singer – all 5’ of him had a good strong voice and wasn’t too dissimilar to Steve Perry, and jumped around the stage like a jack in the box trying to get some reaction from the crowd.
Then Deep Purple came on and the atmosphere was completely different – thought the singer was even better than last time, they were amazing AND I got my drum solo to boot.
