Well, well, Bert - you are coy. Surely we can give the troops a website?
Visit www.floraldance.com, you confused people (including most Cornish postings). The book is by a Cornish singer and musician, Ian Marshall, and believe me he knows everything. You can buy the book online or by telephone.
What is most interesting is that he shows that most Cornish bands play the wrong version of the proper tune, and not even band conductors or players realise it, let alone Cornish people in general.
