I went along to SNP Headquarters tonight to attend a book launch. It was a book by Gordon Wilson, former MP and former SNP leader. His book is entitled "SNP: The Turbulent Years 1960 to 1990". I don't suppose he really is arguing that we stopped being turbulent in 1990 and he certainly talked about the many ups and downs of the SNP. John Swinney spoke at it and we all just spent a few moments thinking about how far we have come. Anyway I had to dash back after 20 minutes for another meeting so it was very brief but I am looking forward to reading the book.
