During a U2 concert in Abuya, Nigeria, Bono asked the audience for total quiet.
Then in the silence, he started to slowly clap his hands. Once every few seconds. Holding the audience in total silence, he said into the microphone "Every time I clap my hands, a chicken in a stove, fries."
From the front of the crowd, a broad African accent pierced the quiet: "Clap fastah, mahn"
