Hi, Liland - I bought the paperback "shorter" New Oxford Book of Carols a while back, when the full version was only available in hardcover for well over a hundred bucks. There's now a paperback edition of the full book - it's available at Barnes & Noble (click) for $23.96, or you can get the shorter one for $16.95. Sorry, can't find the Provençal lyrics anywhere.
