Usher hall website seems to still be selling them?
Thanks man. Now the difficult decision of whether to buy them and try and sell the (semi decent) seating tickets or just stick with what I've got...
Still tickets for London on Eventim as at 2:50pm, just bought standing for Monday. Bit cheaper than Tickemaster as well.
Thanks! I got so angry at the fees on the first site that I couldn't bring myself to buy the tickets, but I went for this. (probably was only about £2 cheaper overall, but it's the principle!)
