Jim.
I can only speak from my own experience, and in doing so I have been fair and pointed out that I have never had any problem with Bob Davenport.
I have been even handed about EWAN and pointed out a good experience as well as a negative one.
I have never had any problem with his stage name, after all bob dylan and johnny handle use one, neither do I have any problem with any of Ewans professional presentation including his use of a chair, I think his ideas about vocal warm ups are good too, and I have said on previous occasions how good I thought some of the radio ballads were.
