My challenge is to give a donation to charity each month in 2016. My chosen charity for August is Streetwise Opera who transform lives through music. They work with people who have experienced homelessness and other members of the community running workshop programmes across England staging critically-acclaimed operas. I am particularly impressed with their recent project - With One Voice - an international movement which seeks to build the arts and homelessness sector globally through exchanges in policy and practice. A With One Voice choir sang in Rio on the final day of the Olympic Torch relay. Find out more here
