Well: I'm from Airdrie and the accent changes from one side of the town to the other

I don't think it is off topic, because to those who say "you shouldn't sing songs unless you were born or raised in a particular area", I would ask: where do you draw the line? Should a person from Liverpool not be able to sing a Manchester song, or vice versa? The two accents are markedly different and can be distinguised even by a person who doesn't come from either city.
