G'day,
Gilbert was one of the Ben Hall gang, see also The Streets Of Forbes, but note that the DT version could do with some correcting.
The poem above has been recorded as a song by "Wallis & Matilda". They made some albums of Paterson's poems set to music. Their name is an obvious play on Words, "Waltzing Matilda" being a Paterson song. W&M also recorded a version of "Lost" as a song.
And let's finally get the name Andrew Barton "Banjo" Paterson spelt right :)
Cheers,
Alan
