Blues artists outside the States are faced with the problem of how to deliver the blues vocally. Most(?) choose to adopt some sort of black American vocal affectations - which I don't like; however, some do it so well that even I have to forgive them. The wonderful, afore mentioned Jo Ann Kelly is a case in point. I've included a link to Liverpool, UK, blues artist Raphael Callaghan. He has got his own very interesting take on the blues.
