My understanding of Julie Murphy's words is as follows:

As I was a-walking one fine summer morning
The fields and the meadows were decked and gay
The turtle doves and small birds in every bough a-building
So early in the Maytime at the break of the day

Hark says the fair maid, the nightingales are singing
The larks they are taking their flight up in the air
Come play to me a tune all on the pipes of ivory
The sun is just a-glimmering, arise my dear

Arise arise arise and pick your love a posy
All of the sweetest flowers that in the garden grow
Tis I will pick you posies both lily white pinks and roses
There�s none so sweet a flower as the lad I love

Oh why should my true love be banished from me
Or if he should die and I shall never see him more
It is my cruel parents that look so slightly on me
Because of the colour clothes that my love wears


You'd think the last word would be "wore" but never mind. If anyone would like to correct any of this please do.
