Go to Wythenshawe? I'm born, bred and live here thanks;)i dont agree, plenty of people talk like that, not as strong maybe. my mum was brought up in levenshulme and lived in burnage swell and i know people from all over manchester that talk that way. its just a manc accent, but liam gallagehr exaggerates it a bit. depends on the area aswell, for example didsbury lots of people dont have the accent, go to the wythenshawe and its really strong.
All I was saying is that he tends to exaggerate the Burnage dialect much more. Maybe it's because the 90's or whenever it was was cool to come out of Manchester and talk and chew gum with your mouth wide open at the same time;)
