Sumer Is Icumen In

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