I love Kate Rusby's "The Wild Goose" too. Here are the chords for the song (as I figured them, in the key of D)

Verse:

D G D Ever see the Wild Goose sailing on the ocean

A D G A D Ranza, boys, oh ranza ray

D G D Just like them pretty girls when they get the notion

A D G A D Ranza, me boys, oh ranza ray

etc.

Chorus:

Bm G A Oh ranza, you'll rue the day

D G A D As the Wild Goose sails away

Bm G A Oh ranza, you'll rue the day

D G A D As the Wild Goose sails away

That's pretty much it!
