"One of the things we used to hear a lot on the old Harvest Home forum was that a lap-top computer was just as valid an instrument for folk music as a concertina."

Quite possibly, but that doesn't make any music made on a lap-top "folk", any more than any music played on a concertina is folk.

SS, apart from "drone, rhythm and melody", which are features of pretty much all music, not just folk, can you please explain what elements of your Fylde Beach track you consider qualify it to be "folk". Then we might understand your perspective.

Also, could you explain why it is so important to you that it should be described as "folk"?
