Sorry to hear it. Roger Nicholson was an early influence & remains a continued inspiration. One of my all time treasures is his 1976 Leader album Times and Traditions for Dulcimer (the sequel to Nonesuch) featuring both Jake Walton and occasional contributions from Andrew Cronshaw. I also have a duo album he made with Jake entitled Bygone Days on Fronthall Records from 78/79 - featuring both Lorraine Lee and Bill Spence - recorded in Bath and America.

If you're interested, I can do you copies on cassette (remember them?) or if pushed it might just be the excuse I need to do a digital transfer.
