I've been asked to accompany this hymn at a wedding service. However, the version requested is not the one I'm familiar with (for example, as sung by Hayley Westenra here: http://www.youtube.com/watch?v=EoyvKgVywT4 )

All the videos I've checked seem to have a similar melody to Hayley Westenra's version. Does anyone know where I can find a sound file or video of the other melody to which this hymn is sung?

Thanks, Don
