REM are firing up “Orange Crush”, their veiled commentary on the plight of a promising young buck packed off to serve in Vietnam, and 40,000 people are on their feet, high-clapping for all they’re worth. Later, Michael Stipe will urge everyone to “put your hands up in the air” prior to a song about a dead comedian and lunar conspiracies. “Man On The Moon” kicks in, and everybody starts hugging each other. Hugging! This seems too weird. Since when did REM become everyone’s favourite feel-good stadium band?
