I am so sorry to hear the news about HH.
I never met him sadly nor indeed anyone from HG on any of the outings however over the time I spent here I found him knowledgeable, helpful, natural and very funny.
I asked him about his signature and he couldn't remember but I suspected it was to do with me saying once that I talked too much.
My sincere condolences to his family and to all who knew him here.
