Cuckoo Song

Cuckoo Song

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!
