Marion, I can't get into the page you have given to answer your question but I also think that you are confusing the Silver Spire with the Silver Spear they are both pospular reels and I know a number of people who have confused the titles. To complicate matters, I have a feeling that the Silver Spire is also known as the Golden Keyboard.Hesparis, it is not my day for getting into web pages (I had intended to provide a link from JC's search) but both the Swallow's Tails (jig and reel) exist. The reel is another one of my favourites. I learnt is from a Dubliners LP where Barney McKenna plays it with the High Reel.
