Simple teach track.
Just the Soprano/Alto/Tenor parts. (sorry Basses, but those parts were quite similar to each other).
Hopefully there will be a better sung version coming soon...
This is a combination of the orginal score, with the extension inserted at the appropriate place including having the second verse music repeated with the additional lyrics spelled out longhand
Thanks to Mark Moys for sharing this
