See the following links -
Huge numbers of people attended the re-enactment.
The main point is a simple one - the event was organised by the Bannockburn and Districts Lions Club. As discussed in my blog entry 'Clan Gunn Society Australia' (of 1 June 2014) Scottish cultural preservation can happily exist outside of Clan societies and is doing so in places like Australia.
12 August - and further shown by the Exhibition 'For Auld Lang Syne' held at the Art Gallery of Ballarat 11 April 2014 - 27 July 2014 which celebrated Scots in Australia from the First Fleet to Federation. As said, Scottish cultural preservation does not require Clan societies; this raises the question as to the role of Clan societies overseas. Is it anything much more than genealogy and biography?
