The Academy was heaving, the floor was so sticky with beer that lifting one’s feet was an effort, and the crowd were beginning to lose patience. Frederick “Toots” Hibbert and the Maytals were late; a 9pm start for this London show was scheduled, but the appointed hour had come and gone, the minutes were ticking by, and the DJ’s efforts to keep us entertained with a string of ska and reggae classics were beginning to fall on stony ground. There was even some booing. Had it not been for the blast of cold air from the super-efficient air conditioning system that kept things chilled, tempers would almost certainly have begun to fray.
