Sumer is icumen in,
Lhude sing cuccu!
Groweþ sed and bloweþ med
And springþ þe wde nu,
Sing cuccu!
Awe bleteþ after lomb,
Lhouþ after calue cu.
Bulluc sterteþ, bucke uerteþ,
Murie sing cuccu!
Cuccu, cuccu, wel singes þu cuccu;
Ne swik þu nauer nu.
Pes:
Sing cuccu nu. Sing cuccu.
Sing cuccu. Sing cuccu nu!

Современный английский текст:
Summer [bad word] in,
Loudly sing, Cuckoo!
The seed grows and the meadow blooms
And the wood springs anew,
Sing, Cuckoo!
The ewe bleats after the lamb
The cow lows after the calf.
The bullock stirs, the stag farts,*
Merrily sing, Cuckoo!
Cuckoo, cuckoo, well you sing, cuckoo;
Don't you ever stop now,
Sing cuckoo now. Sing, Cuckoo.
Sing Cuckoo. Sing cuckoo now!
