The better-known song of this title goes as follows - I am surprised it is not in the DT already:

BLACKBIRDS AND THRUSHES

If all the young ladies were blackbirds and thrushes
If all the young ladies were blackbirds and thrushes
Then all the young would go beating the bushes
Rye fol de dol diddle dol diddle dol day

If all the young ladies were ducks on the water (x2)
Then all the young men would go swimming in after
Rye fol de dol diddle dol diddle dol day

If all the young ladies were rushes a-growing (x2)
Then all the young men would get scythes and go mowing
Rye fol de dol diddle dol diddle dol day

If the ladies were all trout and salmon so lovely (x2)
Then divil the man would go fishing on Friday
Rye fol de dol diddle dol diddle dol day

If all the young ladies were hares on the mountain (x2)
Then men with their hounds would be out without counting
Rye fol de dol diddle dol diddle dol day
