Summer is Icumen In

With Rebecca and Lizzie.
Rise Up Singing chapter: Rounds, p.192

Pronunciation guide: þ = th. 'u' can be a [u] or [v] sound. Guess the rest, and the people who will bother to correct you are 90% likely to be pompous.

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 þu singes cuccu; Ne / swik þu nauer nu!
