Saturday night in South London Hundreds of young people are gathering for the latest craze An acid house party in a disused warehouse Coaches will take them to a destination Which is deliberately been kept secret to evade the police Wait, where you think you're going to? Must be told We don't know, it's like mystery (that's the mystery of acid) This is acid, man This is acid, man But it was a earlier party in a peaceful setting of Sevenoaks in Kent Which led to the most controversial policing so far A raid on an acid house party ended in violence And led to over 20 formal complaints against the police At midnight about 60 policeman arrived A group of them burst into search for drugs It was alleged but none of the group were in police uniform The first thing I saw, well What I prepared to be was a bunch of hooligans Coming charging through the door With big black sticks flailing in the air shouting "Get on the f-ing floor you lowlifes!" The people, that didn't get on the floor Immediately were just beaten on the floor, beaten to the floor It was incredible, incredibly mindless violence They were beating me as they took now They weren't just roughly handling me and any other policeman That passed on the way Were taking a good sort of potluck punch of me as well They were manic in there, it just terrified me And everybody who was there was really frightened Wait, where you think you're going to? Must be told We don't know, it's like mystery (that's the mystery of acid) This is acid, man This is acid This is acid, man This is acid This is acid, man This is acid This is acid, man This is acid This is acid, man This is acid This is acid, man This is acid This is acid, man This is acid This is acid, man This is acid This is acid, man This is acid 30 something years later
