THE PERPETRATOR The Chemical Brothers' Ed Simons (left) THE PROOF ''It Began in Afrika'' (from 2002's ''Come With Us'') THE PLEA ''It was a big single, a big dance record, but it didn't make our greatest-hits compilation just because it's so annoying. It goes 'Afrika-ka-ka' -- that's the only vocal in it. It's a sort of percussion, acid workout. It was a big record in clubs and we [performed] it for about four years, and every time I hear it I just shudder because there's only so many times you can hear that booming 'It began in Afrika-ka-ka!' Just hearing it immediately bugs me. It was a great record for the summer, and that's all it needed to be.''
