I guess it depends on what one considers a purist. Anyone that tells me how I have to interpret a song won't get very far. But if by purist you mean that you like a specific type of music done in a traditional manner, I agree that you have every right to enjoy that music in the manner you choose. And anyone that sneers at your right to enjoy the type of music, and the interpretation, is an idiot.

But, as a performer, I will perform it the way I hear it in my head. I often have my foot in both camps. I can, and do, perform trad folk music. But I also perform modern "folk" singer songwriter stuff. For me it has to do with whether it is a good yarn well told, or a feeling well expressed.

The key here is tolerance of, and respect for, each others musical tastes.

All the best,

Mick
