Here is an idea for what it is worth that I been doing. Record the songs that you really like, the long ballads on the net like myspace or one of the others. What I been doing when performing it tell them where they can listen to the songs and other songs. Then if people ask me on a long ballad I will do it the next time I perform out ... People been asking for Blue Mountain and I drag that one out pretty long but they like it ... helps me figure out what ones if any I should do by looking at the downloads I get and the repeat listens ... Just a thought
