I sang unnaccompanied mostly. I usually had an old 5 string banjo with me but didn't do anything fancy with it - just simple 2 finger style back-up for some songs. Mainly it was just a prop. My voice is high and clear enough to cut across city noise so that was an advantage. I was terrified before every time - over 7 or so years, but I found that if I dressed up in some kind of easily recognizable outfit and strode confidently into the very middle of the main street and started singing - nothing bad happened and people smiled and welcomed me. It was a matter of theatre really while playing myself. Wonderful times. Wonderful memories. Joy
