Here are the lyrics as sung by Robin Hall and Jimmie MacGregor (at least on the record that I have). They are different from those in the DT.

HARES ON THE MOUNTAIN

If a' the young girls were like hares on the mountain, (x2)
Young men would take guns and they'd go out a-huntin'
Sing whack-fol-a-diddle-i-do, whack fol-a-day. (x2)

If a' the young girls were like blackbirds & thrushes,(x2)
Young men would take sticks and go beat in the bushes.
Sing whack-fol-a-diddle-i-do, whack fol-a-day. (x2)

If the girls were a' trout and salmon, so lightly,(x2)
Then divil a man would eat fish on a Friday.
Sing whack-fol-a-diddle-i-do, whack fol-a-day. (x2)

But I fear the young men are like dew on the corn,(x2)
At night they are with ye, in the morning they're gone.
Sing whack-fol-a-diddle-i-do, whack fol-a-day. (x2)
