Harvey, well said as usual!
Nicheless, go and find an acoustic gathering. If not advetise and set one up. I have one in my local town (Richmond -upon -Thames.) It is an eclectic mix of singer song writers, poets, newbie's and top flight artists. I go and perform. I like you have a very mixed repertoire. I play: Jazz, folk, jugband, cajun (Fiddle), blugrass, Latin, Bossa, acoustic blues. I go and sing what I want. If there are alot of say folkies on a particular evening i will play/sing jazz. Or if there is a mix of jazzers/folkies i will play some arabic stuff Benbow taught me. You have the keys to make yourself a cut above the rest. DON'T GET DISHARTENED. I did that a long time ago and wanted to give it all up - then i met Steve (My mentor) and he showed me how to enjoy and work an audience to MY way of things. (Some will argue this point) sometimes you have to say "f**k the lot of you." you have to play/sing what you want to do. You are there also to enjoy yourself!!
