U2 - Zooropa Tour @ Wembley Stadium '93.
Bono went over on a live video link to Sarajevo, for about 15 mins, talking to these refugees/war victims, half way through the concert.
...the only time i've been to a Stadium show, where vast numbers of people were loudly booing in unison.
Not content with alienating the paying crowd further, Bono decided to interupt the show again, by getting Salman Rushdie, up on stage.
It felt like a party political broadcast - not a pop/rock concert.
I left early, along with thousands of others.
