Good threads never die.They just have a rest.
They're both great versions - Shane's version has the power that goes with it being the fella that wrote it, whatever he sounds like singing it, and Kirsty has a great voice. But that version came across as a great record, and one you'd want to hear it again.
On the other hand, Christy's version liberated the song from the turntable or the CD player. That means that now it's a song you expect to hear people sing, or to sing yourself if you're up to it. I don't know how it works, but that's what seems to happen with songs he sings, and it doesn't happen with lots of other great siongers.
