In 1988, when Olga Callaco was asked to take on the role of a conductor for The Cantata Choir, a cosmopolitan group of singers, it was supposed to be a three-month stint. “I was simply filling in for Dr Fareed Curmally, a pianist who was doing the job back then,” says Callaco. Curmally, son of Mehmood Curmally, owner of Mumbai’s erstwhile gem Rhythm House, was back then doing his MD (Doctor of Medicine), and was supposed to return in the next couple of months. “Curmally knew my daughter, Natasha quite well. So, on his request, we decided to become a part of it,” she says. While her mother is the conductor of the choir, Natasha has been with the group as a soprano singer since then.
