Solstice

Sing, cuccu, nu. Sing, cuccu.
Sing, cuccu, nu. Sing, cuccu.

Sumer is i-cumin in,
Lhude sing, cuccu!

Groweth sed and bloweth med
And springth the wude nu.
Sing, cuccu!

Awe bleteth after lamb,
Lhouth after calve cu,
Bulluc sterteth, bucke verteth,
Murie sing, cuccu!

Cuccu, cuccu,
Wel singes thu, cuccu.
Ne swik thu naver nu!

Sing, cuccu, nu. Sing, cuccu!

If your Middle English is rusty:

Summer has arrived,
Sing loudly, cuckoo!

The seed is growing
And the meadow is blooming,
And the wood is coming into leaf now,
Sing, cuckoo!

The ewe is bleating after her lamb,
The cow is lowing after her calf;
The bullock is prancing,
The billy-goat farting,
Sing merrily, cuckoo!

Cuckoo, cuckoo,
You sing well, cuckoo,
Never stop now.

Sing, cuckoo, now; sing, cuckoo;
Sing, cuckoo; sing, cuckoo, now!
