I think Gibb Sahib is (rightly) making the point that most of the song choices seem not to be shanties. Personally I would not bother with "South Australia" as it is so hackneyed. Sort of the shanty equivalent of "the Wild Rover".

Another good learning resource for shanties is the recordings of the Keelers. And Collins Knights & Mageean.

If you want slicker arrangements try Pint and Dale although their stuff is usually accompanied.
