I would definitely agree to buy the European version as the bonus tracks are well worth it--hearing the great versions of Mother of Love and Ellan Vannin (perhaps the best song he's ever done in all time!!) as well as the weird "Christmas Eve & Halloween" make it a real treat and well worth a little extra.
Numerous people for whom I have played the music can't believe how wonderfully he handles the old English carols and how haunting some of them really are, especially In the Deep Midwinter, which is my fave.
