He was playing a U2 concert in Glasgow, Scotland when he 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 says into the microphone,
"Every time I clap my hands, a child in Africa dies."
A voice with a broad Scottish accent, from near the front of the crowd, pierces the silence ...
... ... ... ... ... ... "Well, ... stop doin' it then!"
