The article you mention is probably one that I wrote some years ago for Musical Traditions. It is article 184, 'Bob Blake and the Reinvented Self'. The article is still available on-line. The reference to Kennedy is this short passage: 'On one occasion I mentioned to Peter Kennedy that I knew Bob and was surprised to find that Peter did not share my enthusiasm for Bob's singing. It never entered my mind that Peter may have known something about Bob that was unknown to me.'
