Move to live elsewhere — it’s concerning Yorkshire town (8)
I believe the answer is:
resettle
'move to live elsewhere' is the definition.
(settle in another place)
'concerning yorkshire town' is the wordplay.
'concerning' becomes 're' (both can mean on a particular topic).
'yorkshire town' becomes 'settle' (Settle is a town in North Yorkshire).
're'+'settle'='RESETTLE'
'it's' acts as a link.
(Other definitions for resettle that I've seen before include "Take up living in a different place" , "Move to new state" , "Move home" , "Move to live in a different place" , "Colonise again" .)
