It seems that "strong" rumours are being whispered in Australia that LFO and WNO's Anthony Negus may take the presently, and so suddenly made, vacant podium to conduct the Melbourne Ring cycle.
Given that Opera Australia are very unlikely to get the other realistic option - Simone Young - Negus' undisputed long experience of conducting Wagner and that he will have concluded LFO's Ring cycle on July 12, mean these rumours may not be as far fetched as they may seem - even to an international circuit perhaps not that familiar with his Wagner.
It should also be noted, that as someone that worked with Goodall at WNO, has conducted Tristan, Das Rheingold, Siegfried, and Götterdämmerung with the same house, and a complete Ring cycle with LFO, he maybe one of the few conductors with enough experience of Wagner's work to step in at such a late stage. It might also be noted that he has conducted concert performances of Parsifal already in Australia - Wellington with the New Zealand Symphony Orchestra. He thus has some "local" experience.
OA have neither confirmed nor denied the rumours
