Green back to rock his patch.
The 28-year-old took to the main stage at the free music festival in the Hackney Marshes, east London to perform hits like Remedy and Just Be Good To Green.
"Being a Hackney boy, I didn't know I could come back and perform to a crowd of this size," he said.
The rapper - whose real name is Stephen Manderson - added: "I played football here at the marshes but they put me in the goals because I was rubbish."
Florence and the Machine also performed yesterday with another mesmerising live set.
But Hackney rapper Plan B - also known as Ben Drew - slipped on the stage several times during the downpour that coincided with his set. The rain did not deter music fans, however, with around 50,000 people estimated to be attending.
