The tune I was teaching in the beginners workshop on Friday was called Blowzabella, here are some links to a video, dots and midi files. I did simplify it slightly, and used an open string in place of the high G. http://www.youtube.com/watch?v=IG_dN6xb4sYhttp://abcnotation.com/tunePage?a=www.a ... 01823/0136 http://www.andyhornby.net/Winders.html
