That is your opinion to which you are welcome - I've seen Sail Pattern several times - though not for a while. I remember loving their version of Spanish Ladies. I also love the original. Both can exist not just the version you prefer. The Sail Pattern version may pique the interest of people who might not have heard the song before and who may wish to find out more about it and possibly then about other folk songs. That is how the tradition will survive - not through a group of ageing people (of which I count myself as one) sitting round in a room bemoaning the fact no one wants to join their merry crew
