Last year, Cairo's Tahrir Square in Egypt rang out to the sound of violent protests over President Mubarak’s rule.
Now, the sound of music can be heard from two troubadours, who’ve taken up performing at the square's tent city protest.
Fouad Hady meets Ahmed Moses, Hany Bade and their supporters, who spend each night in the square singing their message of peace and unity.
One is a Muslim and one a Christian, so they’re calling too for an end to the sectarian clashes that have followed Egypt’s revolution.
