As I talked to the McCallums in May this year, I had to keep reminding myself that they are both in their nineties and that they've been in the business of entertaining us for over seventy years. Anyone who saw them in any of the films or plays in which they co-starred will know how well they played together professionally. As you watch them together now, complementing (and complimenting) each other, you can't help wondering how much of their professional success was a spin-off from a stimulating partnership off-screen or off-stage. It seems timely to pay tribute to them for what they achieved in the performing arts in Australia and elsewhere.
