This is a very usable Christmas collection of vocal duets for two medium voices. The accompaniment CD contains piano tracks for each title, and is an invaluable way for vocalists to practice or perform. Contents are: Joy to the World; The First Noel; What Child Is This; O Come O Come Emmanuel; God Rest Ye Merry Gentlemen; Coventry Carol; Come Thou Long Expected Jesus and Christmas Angels (a medley of Angels We Have Heard On High with Hark! The Herald Angels Sing).
