The neighbouring countries have been fighting for several decades, but Bono is hoping Peres can continue to be a voice of reason in the Middle East even though he is no longer in charge, and during a concert in Toronto, Canada on Monday (06Jul15), which Peres attended, the rocker called on the politician to work towards peace.

Bono said, "We understand President Peres, that you have tried to be the voice of reason. And you've dedicated a lot of your life to try and bring peace in this really dangerous region."

He told the crowd, "(He is) somebody who is active as the voice of reason in a region where the loudest voices are often the bellicose ones. We wish that you... don't give up the two state solution."

Bono and Peres also met backstage before the concert.
