The Rolling Stones were scheduled to play at a free concert for Blackhill Enterprises in London's Hyde Park, two days after Jones' death; they decided to go ahead with the show as a tribute to him. Jagger began by reading an excerpt from Shelley's poem "Adonaïs", an elegy written on the death of his friend John Keats. They released thousands of butterflies in memory of Jones before opening their set with "I'm Yours and I'm Hers", a Johnny Winter number. The concert, their first with new guitarist Mick Taylor, was performed in front of an estimated 250,000 fans. A Granada Television production team filmed the performance, which was broadcast on British television as "The Stones in the Park". Blackhill Enterprises stage manager Sam Cutler introduced the Rolling Stones on to the stage by announcing: "Let's welcome the Greatest Rock and Roll Band in the World."
