Tomorrow shall be my dancing day, John Rutter

'Tomorrow shall be my dancing day' from Dancing Day by John Rutter, performed by the Schola Cantorum of The Cardinal Vaughan Memorial School with harpist Zita Silva on its recording of music of Christmas music for Boys voices and harp, Hodie!.
Tomorrow shall be my dancing day
Tomorrow shall be my dancing day:
I would my true love did so chance
To see the legend of my play,
To call my true love to my dance:
Sing O my love, O my love;
This have I done for my true love.
Then was I born of a virgin pure,
Of her I took fleshly substance;
Thus was I knit to man’s nature,
To call my true love to my dance.
Sing O my love...
In a manger laid, and wrapp’d I was,
So very poor, this was my chance,
Betwixt an ox and a silly poor ass,
To call my true love to my dance:
Sing O my love...
