Does anyone know how the Daily Mail got their scoop on the story....

 

Was it a leak from the authorities with whom Coldplay needed permission to shoot? (I'm guessing they needed permission for a stage on the South Bank and a boat moored in the THames for nearly 3 hours in one place).

 

Or was it just good detective work by a pap?

Somebody will have tipped them off.

there's always somebody in the know willing to make a quick buck.

Simon Pegg's tweets might have sparked interest - the paps would have had 8/9 hours from the time of that tweet to find something going on on the Thames using twitter as a resource.
