I've been looking at Reginald Heber hymns & have become facinated by the additional verses rich r posted for Brightest and Best.

The Southern Harmony does have the additional 3 verses with The Shepherd's Star. That particular setting is not the usual "Star in the East" tune that most use from the Southern harmony. Both use the anonymous "Hail the blest morn" for the first verse. Star in the East uses "Brightest and Best" as the chorus while Shepherd's Star completely omits Heber's first verse.

These verses are not in Heber's collection that was published in 1827, the year after he died. I've been coming across a date of 1811 for the words & it may be that he did include them in some earlier version of the words.

There's some additional discussion in This thread, but I don't see where any of the full versions have been posted.
