Pub dispute getting heated audibly in Cumbrian town (6-2-7)

'cumbrian town' is the definition.
(I've seen this before)

'pub dispute getting heated audibly' is the wordplay.
'pub' becomes 'bar' (both are drinking establishments).
'dispute' becomes 'row' (row is a kind of dispute).
'getting heated' becomes 'in furnace' (getting heated in a furnace).
'audibly' shows a homophone (sound like).
'infurnace' is a homophone of 'infurness'.
'bar'+'row'+'infurness'='BARROW-IN-FURNESS'

'in' acts as a link.
