If you are looking for a tuneful large-scale choral work to perform with your choir - you might like to consider a new SATB arrangement by John Whittaker of Vaughan Williams' Folk Songs of The Four Seasons' (duration 50 minutes) - which was originally written for just upper voices. This arrangement has been successfully performed earlier in the year by Vox Philia under the direction of David McConnell. You can view/listen to extracts of this performance via Youtube.
