I have just been browsing through this thread again and Jack King and Roger Fleming brought back some memories to me of evenings spent in CSH in the mid sixties. I remember one evening when Peter Kennedy , in the absence of some guest for whom he apologised, took up a guitar and sang an Irish Comic song "Mick Maguire".
I remember how he played a little intro , finger style before singing. Another evening we were treated to a guitar workshop by Jimmie McGregor and a young lady (I think Liz Turner) also accompanied him in some songsafter the lesson. Do you guys remember either of those events ?
I also remember a group called , I think, "The Coachmen" or "The Highwaymen" , a trio all with guitars which included a black bearded German sounding chap . I wonder if he was the Karl that you speak of Roger ??
I would say that it was c.1963/4.
