Glenn, if you're looking for material to perform, you have to give us more clues. There are so many sub-genres of 'blues' that it's hard to know what you might consider suitable material for you to perform. For instance, I never really considered 'Kansas City' a blues (in the traditional sense) but what might be considered 'blues' by some might be considered 'R&B by others, 'Rock&Roll' by others, and 'Pop" by others. If one were listing favorite blues singers, Joe Cocker's name probably wouldn't come up YET, he's definitely one of MY favorites, along with Janis Joplin, both of whom most people would consider 'Rockers'. See, that's the name of the game in music, SUBJECTIVITY, SUBJECTIVITY, SUBJECTIVITY. What makes it great (and loads of fun) is that NOBODY'S WRONG .
