...to skip Australian guitarist, Moss - a statesman (10)

I believe the answer is:

missourian

I'm a little stuck... Click here to teach me more about this clue!

'statesman' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe there's an association between them I don't understand?

'to skip australian guitarist moss a' is the wordplay.
'to skip' becomes 'miss' (I've seen this in another clue).
'australian guitarist moss' becomes 'ouri' (I can't explain this - if you can you should give a lot more credence to this answer).
'a' becomes 'an'.
'miss'+'ouri'+'an'='MISSOURIAN'

Can you help me to learn more?

(Another definition for missourian that I've seen is " American".)

I've seen this clue in the Sydney Morning Herald.
