Andy7 ( are there really 6 other Andyies?) I like your measured approach.
Most of us don't have voices or playing ability to rivet people to their seats for anything more than 3 minutes. I play lots of east European tunes - but they are difficult listening - so I mostly don't play them in public.
If I was writing a manual for playing in public I think my number one chapter would be ' consider the audience'. Playing in a public bar on a Friday night needs a different approach to performing for singers in a singers club. I think most of us know that - but its an easy mistake to make.
