Cuban supporters hold up photos of Cuban Revolution leader Fidel Castro as they dance during a concert of international artists on the eve of the 85th birthday of Cuba's Revolution leader Fidel Castro in the Teatro Karl Marx August 12, 2011 Havana, Cuba. The three hour 'Serenade for Fidelity' (Serenata a la Fidelidad) was organized by the Foundation Guayasemin from Ecuador and the Cuba Ministry of Culture. Fidel Castro fell ill in July 2006 and has stepped back from power, handing over power to his younger brother Raul Castro.
