Age check?

      Remember Jimmy Shand; without looking him up?  These keep recurring under the Yew.  I, and probably most English, know them as Harebells.
BUT
      "Campanula rotundifolia, the harebell or common harebell, Scottish bluebell, or bluebell in Scotland, is a species of flowering plant in the bellflower family Campanulaceae."  Until today, I wasn't aware they were Campanulas.
      OK!  What about Jimmy Shand? Well Jimmy Shand played "The Bluebell Polka" - BUT - I'll bet a £1 to a pinch of ***** that it was this Bluebell they meant and not Hyacinthoides non-scripta?
