Sumer is icumen in,
Lhude sing, cuccu!
Groweþ sed and bloweþ med
And springeþ the wude nu.
Sing, cuccu!

Awe bleteþ after lomb,
Lhouþ after calve cu,
Bulluc sterteþ, bucke ferteþ.
Murie sing, cuccu!
Cuccu, cuccu,
Wel singes þu, cuccu.
Ne swik þu naver nu!

Sing cuccu nu, sing cuccu!
Sing cuccu, sing cuccu nu!
