In answer to Geoff Lawes, no that's not Jim Reid singing in the YouTube link you gave: it's Daniel Kelly (as it says in the script accompanying the video!!) and he does make a nice job of it, though he has a deeper voice than Jim's.
You might like this track of Jim singing: the songs are seasonal anyway and include what is perhaps his best-known setting of a Violet Jacob poem - Norland Wind (aka The Wild Geese):
