He makes the statement, in his words (and in our badly and hastily translated German) "... before even more wild speculation and rumours are circulated"
After his break - which has lead to a number of cancellations - doctors inform him that he is now making an excellent recovery and that he will be able to meet his obligations starting in July with Linz and with Munich and Salzberg now all firmly in place.
While it has taken a little time to shake the infection that he had and he is sorry for disappointing his fans, he thanks them for all of the well wishes he received and hopes that they can understand his reasons for the cancellations.
