Apart from 'canny', which is mainly used only in the north of England and in Scotland these days, there is no dialect, as such, in the unprovenanced text Alec has posted; all of the words are standard English, though some are given "dialectal" spellings to reflect local pronounciation. That may seem over-particular, but it's a useful distinction to make if you are going to start giving people instructions on pronounciation and so on.

Where did you get it? As Stewie mentions, there are further references, and other, longer texts, in the old discussion indicated, while the "Yorkshire version" is a set of 'Six Jolly Miners' that includes two of the verses you quote. It can be seen at MINER LAD.
