In a column for The Big Issue, the Pulp frontman said that he "could have kissed" the festival organiser who told him about the Indignados in Spain who had been evicted from an Occupy camp.
"That was my first encounter with the Occupy movement - a visionary movement because it recognises that it's the cult of the individual that got us here, and so to escape from this situation is going to require collective action," Cocker said.
"Much is made of the fact the Occupy movement doesn't have leaders, and this is sometimes depicted as a failing. It is actually one of its main strengths."
He added: "We are over leaders. We are not interested in ideology anymore - we just want things to work properly and fairly... Occupy shows a new way. Whether you recognise it or not yet, it's what you want."

Def Jam Recordings co-founder Russell Simmons, rapper Kanye West, Radiohead's Thom Yorke and Massive Attack have all visited Occupy protests since the movement started.
Actor Martin Sheen has said that the Occupy movement is an "inevitable expression of the despair and equal measure of hope".
