Probably not true.. but it could be... it should be

Bono, whilst playing a gig in Glasgow, got the whole crowd to be silent and then began slowly clapping his hands. He got the crowd to clap along for a while, the stadium quiet except for the rhythmic clapping...

After a short period Bono spoke, saying that everytime he clapped his hands a child in Africa died...

Suddenly, from the front row of the venue a voice broke out in thick Scottish brogue, ending the silence as it echoed across the crowd, the voice cried out to Bono "Well stop fucking doing it then!!"

Aye!
