I have heard Jane's name mentioned in glowing terms in various traditional singing circles in Scotland, and listened to recordings of her wonderfully clear voice, but never had the pleasure of seeing/hearing her singing live.
We already have at least two traditional singing weekends, the Fifesing in May, run by Peter Shepheard of Springthyme music, and Cullerlie, in her native Aberdeenshire, in July. It would be good to have a presentation in her honour at either or both of these. (No excuse needed!) Apart from the CD mentioned by TS above, I think there are some recordings within the Kist o' Riches ( Tobar an Dualchais).
If it is decided to have some more permanent memorial as suggested by Fred, then it might possibly be housed at the Elphinstone Institute at Aberdeen University where other musical archives are held?
I am sorry, but I don't know of Bobbie Richie either. Perhaps someone who does could start a separate thread?
