Gimme Shelter 
The Stones are on a stage the size of a kitchen, facing a pitch-black hill with 300,000 hippy kids crushing forward. It’s a freezing night, the acid’s turned bad and the only security is the hells angels, who kick off each time they start Sympathy For The Devil. Then... someone’s killed on camera. The bitter end of flower power and you’re watching the dream crumble second by second. Amazing.
