@bobd,
"Sumer Is Icumin In" is one of the oldest, if not the oldest, canons in print (circa 1226)
Sumer is icumen in,
Lhude sing cuccu!
Groweth sed and bloweth med
And springeth the wde nu,
Sing cuccu!
Awe bleteth after lomb,
Llouth* after calve cu.
Bulloc sterteth, bucke verteth**,
Murie sing cuccu,
Cuccu, cuccu!
Wel singes thu, cuccu;
Ne swik thu naver nu.
Summer has come,
Loudly sing cuckoo!
Seeds grow, and meadow blooms
And the woods bud anew,
Sing cuckoo!
The ewe bleats after the lamb,
The cow moos after the calf,
The bullock leaps, the buck farts,
Merry sing, Cuckoo!
Cuckoo! Cuckoo!
Well you sing Cuckoo,
Nor cease you never now…
