In search of the house that becomes ’arse

The poet Ian McMillan presents a linguistic challenge to his friend and musician Ray Hearne. They’re looking for the isogloss - a boundary line where accent and dialect changes – where the pronunciation of house becomes 'arse. It’s somewhere between Sheffield, south Yorkshire and Chesterfield, north Derbyshire and they’re on a mission to find where, why and how. http://www.bbc.co.uk/programmes/b01ljwm4
