I know this isn't a hot deal, strictly speaking. But I noticed that they've released some more tickets left for the Live Earth gig at Wembley this weekend.
I assume there was massive demand for this when the event first went on sale. It's not quite my thing (Madonna and James Blunt?!), but I'm forever trawling ticket sites.
Anyway, at the time of posting there are some £55 tickets left: http://www.ticketmaster.co.uk/event/22003E91AD46858B
Please feel free to vote down if this isn't appropriate - it's my first time!
