We regularly booked Malcolm at Catford, Beckenham, Marsh Green (nr.Edenbridge) from 1963/64 onwards. I have a vinyl LP with the line up as described by John Field but with Carole on autoharp instead of Ian McCann. He was also the presenter for us ("Four Square Circle") whe we used to do the BBC programme, "Country Meets Folk". The first time I ever saw him play flat pick I couldn`t believe a person could be so clean and accurate with an instrument.
Best wishes to him in Norway.
