As a chorister many years ago I recall our organist conducting a vote on whether to use Hereford or its AMR alternative, St Gregory. Hereford was the clear winner. It seems to me quite different in character from S S Wesley's other popular tunes, such as Harewood, Alleluia and Aurelia. It's a pity that the gentle St Gregory has largely disappeared, but perhaps this is partly because the other words to which it was set, 'Creator of the world, to thee', were intended for Septuagesima, although I would have thought that they could also fit the beginning of Lent.
