Wife (bless her) has just returned with 8 £45 tickets - 4 together and 2 pairs (one directly in front of the other). Apparently you get near the front of the £25 queue (I think that's the only queue there is) and then stewards sidle up and ask you if you want any of the odds and sods left from the more expensive set of tickets. Therefore take heart if you want something more than a seat with the Gods.
