Old songs get pulled about, I do it primarily so more people will understand what is going on, I don't fall into the camp that says the song has to be 100% authentic, changing freshens them up a bit and maybe explores different sentiments, it is important to have the original and continuing research into the background of the songs as a point of reference and for others to explore from scratch and not compound the felony......or is that what is called the folk process!
