I suppose most anglophones have heard 'O Holy Night' in one or another version. Most of these versions of 'O Holy Night' feature Adolphe Adam's beautiful melody and either John Sullivan Dwight's English lyrics or the lyrics of anonymous lyricist of the longer unattributed version. Neither of the English versions of the lyrics bears much resemblance to Placide Cappeau's (1808 – 1877) French Nativity poem 'Minuit, chrétiens'. Cappeau's poem is a beautiful French Nativity poem to which Adolphe Adam's melody does full justice, you'll find the text below the fold. It's sung here by the famous Québécois choir La Maîtrise des Petits Chanteurs du Mont-Royal in an absolutely outstanding performance given on Christmas day of this year at the Basilique de l'oratoire Saint-Joseph, Montréal.
I've also included Morten Lauridsen's (b 1943) wonderfully evocative 'O Magnum Mysterium'. Lauridsen composed it in 1994 it's a setting I've come to enjoy more and more but it's not without its difficulties for the singers. The high G that you can hear at 4:33 can be quite difficult to achieve, the choristers of Winchester Cathedral manage it with grace and aplomb. Enjoy :-).
