Hmm, that's kinda strange on many levels...I mean he announces it on the day he again cancels another gig on this supposedly "40 years" - tour without an explanation. That already leaves a bad taste and is a slap in the face for the fans, that had tickets for Perth. But that aside, it's already in January??? How are they are supposed to pull that off? I mean they are professionals of course but they are also touring until mid December. How are they gonna learn all the new songs, when the current ones don't sound completely rounded up yet? And directly after that the rescheduled South American leg is supposed to happen.... I'm sorry, but I can't imagine that going smoothly and hopefully it's not going to be at the expense of the South American fans.
Maybe Johnny's whole best of and so on made him do something like that Quarry gig. I don't know...
