re discussions of didgeridoo (probably a MOCK aboriginal word), it's worth looking at messages at http://listserv.heanet.ie/cgi-bin/wa?S1=gaidhlig-b - click on archives and do a search for Didgeridoo, or just look at the archives for June and July 2002, the main thread is called "Dudaire Dubh = Didgeridoo ?". Most of the messages are in English.
