'The yirraru , of which sixty-eight are presented in this book, were anecdotal songs...The yirraru... were composed about specific events or experiences which captured the emotions or fired the imagination, which the composer shared by describing them poetically and musically...
Yirraru could be sung by anybody, at any time. Some people were gifted at remembering such songs and built up huge repertoires of them, often in several different languages. Alexander Brown is one such person.' Source: Ngarla Songs (2003)
