Could it be they've already given the organisers a heads up they won't be able to make it and they are awaiting for the powers that be at the festival to announce it after they have a replacement?
I've just taken delivery of the Taster Box to trail my favourites for the festival. My favourites so far are the Old Fashioned, Espresso Martini and Margarita.
