Bits that stuck in my mind include a song, allegedly written for the Australian Tourist Board, with the refrain "Come to Australia, you might accidentally get killed...", listing some of the more poisonous and toothy of Australian fauna. In fact, their speciality is songs which show off the fact that they can list things very fast... a good example of this a version of "I've Been Everywhere" where they rattle off a list of Australian place names, and then give it a bit of local flavour by doing a verse of Scottish ones too.
The show is held in a very large and impressively furnished tent with a wooden floor, and the vibration of many tapping feet is apparent - this is good toe-tapping music. They also love to present familiar songs with unusual musical styles, substitution of words and so on. I'd love to tell you more but that would give too much away - suffice it to say that one of their encores was a song called "The Bastard Child of Abba and Frankie Lane" - and I hope that this creates an interesting enough picture in your mind to make you come and hear it for yourself.
The noise of the crowd stomping the wooden floor for more probably carried for miles - two encores well deserved. I hope to meet them later in the festival for an interview... so watch this space.
