About 25 performers in the ChildAid 2015 concert toured the backstage of the Mastercard Theatres yesterday to familiarise themselves with the venue. They were also measured for costumes ahead of the concert on Dec 4 and 5. The performers included those from the Singapore Ballet Academy and the CHIJ (Kellock) choir.
