We've done some workshops at Folk Alliance in the US about presenting traditional music to audience more used to contemporary music. We talk about points in common and play some songs. I also had an idea for a library presentation I called ballads and sketches. I presented mostly ballads and talked about what line/verse drew me to want to learn/arrange the song. I also included a couple newer songs (thus the sketches part of the title). I had that dry run at my house, inviting folklore society and storytelling guild members from the area. I plied them with beer and asked, after the hour presentation, what worked for them and what didn't. So there's ways you can persue trying your idea out. I still have to start trying to sell the show to libraries, but I was happy with the dryrun and feedback.
