Yes, It is ! I know it sounds like a stage name but it really is our name, I'll let you in on a bit of history. Our surname was once Opara, but Great great grandfather so and so (or rather Nonno so and so from Trieste, Italy) loved the Opera so much he changed it. So four generations on, we are now The Official Opera sisters - the only ones in NZ by the way, but NO we can't sing, you can't live by your name alone.
We also aren't long lost children, or cousins of Oprah, unfortunately, but somehow, everybody still refers to us as The Oprah sisters.
