Peace, I think you meant 'Bob Bolton', not 'Bob Coltman'.

Anyhow, the song's title is 'Jail Away Fremantle'. It was written by Wendy Evans and recorded by The Settlers in Perth, Oz.

I am unable to locate my copy of The Settlers 'Bound for Western Australia' which includes the song. Bugsy may be able to help you locate a copy.
