Here you go:

As I was a-walking down by some shady grove
Down by some shady fancy, my heart, my soul's delight

Chorus: Young lambs they were a-playing all on the banks of sweet Mossen
All on the banks of sweet Mossen all on through happy spring
The lark all in the air she rise all the morning
And brings me joyful tidings of my Nancy dear

The song birds on the branches is (sic) now sat down to rest
I'll write to lovely Nancy, my heart, my soul's delight

Chorus

Oh give me ink and paper and I may sit down to write
I'll write to lovely Nancy, my heart, my soul's delight

Chorus

--Stewie.
