Irish sense of humour. Or sense of tragedy.

U2 is in the middle of a concert (possibly in the middle of ‘Pride’). Suddenly,it all gets quiet, all you can hear is Adam’s base on a slow rhythm. Bono starts a slowly clapping with his hands in the air and says:
“Every time I clap my hands a child dies in Africa…”
Three seconds pass while Bono claps. Nobody talks until an Irish Fan yells:
“Stop fucking clapping then.”
