There was a time when I believed that folk music was somehow different and completely unaffected but I no longer believe that to be the case.

When was this? Pre-Playford possibly? Certainly the Dancing Masters of the 18th and 19th century did a lot of "marketing" of their wares.

Sharp wanted folk music into schools and did it a lot to promote folk music both into schools and the theatre. Read his introduction to his music for Midsummer Night's Dream. He "marketed" morris dancing by forming a team and having it travel around the country.

I used a quote from someone else at the top of the post.

The rest was not aimed at you.
