Excuse my limited involvement in the discussion which is because I wanted to hear what people have to say. The questions raised and the songs are important. It's interesting to see not only what songs are considerred influential but also how people respond to the term 'influential'. I do not have a defintion other than to say that it means more than 'songs of protest'. All the questions and responses I read here are important and the non google-able site, when it opens, is not intended to answer those questions but add to the discussion, to provoke and question the very things you are discussing.
In response to Sandra in Sydney's question. The Museum will be opening at old Parliament House in May. The exact name has not been released yet and so is not easily searchable.
By the way Andrez, I'm a bloke not a sheila.
