The band issued an official statement in 2011 when Cohl was involved in a lawsuit with Live Nation.
"Following the end of the 2007 'A Bigger Bang' world tour, The Rolling Stones became free from any contractual arrangements or agreements with Michael Cohl. He is neither their representative nor their tour promoter. Also the Stones confirmed today they have no firm plans to tour at this time.
"The Rolling Stones have recently secured a worldwide merchandizing agreement with Bravado Inc. and in 2008 signed a new global record deal with Universal Music."
