SUMER is icumen in,
   Lhude sing cuccu!
Groweth sed, and bloweth med,
   And springth the wude nu--
   Sing cuccu!
Awe bleteth after lomb,
   Lhouth after calve cu;
Bulluc sterteth, bucke verteth,
   Murie sing cuccu!
Cuccu, cuccu, well singes thu, cuccu:
   Ne swike thu naver nu;
Sing cuccu, nu, sing cuccu,
   Sing cuccu, sing cuccu, nu!
