It's one of the most famous and most widely sung songs in the world, and now it's been arranged for choral groups by Mark Hayes. Includes the opening verse ("When all the world is a hopeless jumble...heaven opens a magic lane."), which sets the stage for that famous opening octave in the melody. The piano part couldn't be better, and the voice writing is impeccable. Fully orchestrated SoundTrax/SoundPax are available.
