The Cuckoo Song

Even though I haven't any guitar chords for this one, I am including this song as the first entry because it is, perhaps, the oldest written English folk song known to have survived the centuries since it was first heard.
The link, attached below, to a youtube video might provide an idea of what it sounded like in the 13th century (although, I think this video might have sounded better without the musical background playing).    The Cuckoo Song video
