There's a whole lot of special events happening at the O2 next week, they appear to be free.
You can get the details here. Details of what's happening on the Sunday, the final day of the Greenwich & Docklands International Festival, are here.
Aside from Snow Patrol, which is discounted, everything else should be free and most of the music is happening in the "London Piazza."
The preview night sounds especially tempting:
Your chance for an exclusive peek around the brand new O2. Live music, performance artists, drinks and once in a lifetime backstage tours. Spend the evening getting into the places no-one else gets to see including the star dressing rooms, VIP areas and executive suites. It’s all open exclusively for you.
The Marley brothers are also there that night so there should be some good music as well. I'll try and get there to have a look around.
