The King's Singers The Library vol. 3. This two-choir arrangement of the Fleetwood Mac hit was created for the large-scale cover featuring the six members of the King's Singers and several thousand members of the ?Stay At Home Choir.? Along with a beautiful and complete arrangement for the King's Singers, there is a full choir along with an Ossia treble part for a mixed ensemble. This is a perfect ?mass choir? selection for singers from elementary school to your top choir.
