I booked John and Julia at Bury St Edmunds folk club, a couple of times ,the first time they did a split booking with Steve Turner, I also brought her to my club after John Clifford had died so that she could get out and play some music.
However there were two couples, George and Eileen Monger and Michael and Caroline Kilbane, who were very supportive after John Cliffords death.
