The climate change campaign 10:10 is launching today - in the Turbine Hall of the Tate Modern on London's South Bank from 4pm to 7pm.
And you've all been invited! (Children welcome.)
There'll be a free gig, with Reverend & The Makers and Stornaway. And free champagne for the first 1000 people to join 10:10.
Just in case you haven't already seen our other thread, 10:10 is the brainchild of Franny Armstrong, who made the McLibel documentary and the climate change docudrama The Age of Stupid, and is backed by various organisations, companies and veeps - including Mumsnet.
Hope to see you there!
