A media event at the end of the Australasia Tour's Korean run in 2008, of the Australian cast in full costume on stage, lined up beside their newly cast Korean counterparts. I know I've seen it, but can't find it anymore.
For that matter, anything from the 2008 South Korean production. I've got stuff from 2011, but not 2008. I know they had in character headshots of everyone, including chorus cats.
