Somer is i-comen in Loude syng cuckow! Groweth seed and bloweth meed And spryngeth the wode now. Syng cuckow! Ewe bleteth after lamb, Loweth after calve cow; Bullock sterteth, buckle farteth. — Myrie syng cuckow! Cuckow! Cuckow! Wel syngest thou cuckow: Ne swik thou nevere now. Syng cuckow, now, syng cuckow! Syng cuckow, now, syng cuckow! 13th century
