I know there is a post from last week relating to this, but this is a different link as the last one only showed the LiveNation dates and I expect this workaround will only work until tomorrow 20/11/08 when these dates go on general sale.
The additional dates have been added for the following venues in 2009:
Nottingham - 12/5
Wembley - 27/5
Manchester - 29/5
Glasgow - 30/5
Birmingham - 1/6
Liverpool - 3/6
Newcastle - 5/6
Now follow the link to the desired date and venue, but it will tell you that there are no tickets available.
Now the trick is to hit the refresh button or press f5 on this page and then as soon as the page starts to load, click the red cross (stop page loading button). You should then see the selection box to select tickets and then complete your order from there.
Please make sure you select one of the new dates listed above. You may have to try the instructions a few times before you get your timing correct, but it does work.
It is such a shame that people have decided to say it doesn't work and then vote cold. As has been proven by others in this post, it does work as long as you follow the instructions and try it several times to get your timing correct.
Anyway, I have been a member of this site for a couple of years now and this is the reason I'm reluctant to post any deals. Oh well, you live an learn (again).
To those that got tickets, enjoy the concert, I know my other half will be over the moon.
