Susan was just making sure that your thread didn't fall off the page, by "refreshing" it (posting a new message) for you.  Perhaps it would be a good idea if you posted the lyrics (with a translation if you have one), as a lot of us are not familiar with the band you mentioned, but might be able to help if you gave us a few clues.  Is this Irish or Scottish Gaelic?  There are quite a lot of songs about people called Sile, as it's quite a common name!
