I love this one and sing it on/near the summer solstice:
MIDSUMMER HYMN Zoe Mulford
Now the days are long and pleasant Do not waste the light Take these moments as a present offered up for our delight Take the gifts the Summer brings us early dawn and dusk that lingers Let them not slip through our fingers Do not waste the light
Now the earth is rich with plenty Do not waste the light Gather in the Summer's bounty ere the season takes her flight Mow the hay and seek the berry, tread the grape and pluck the cherry Once she's done, she will not tarry Do not waste the light
Ere these golden moments perish Do not waste the light Good companions may we cherish while they're present in our sight Let us take in equal measure time for work and time for leisure Friends and family are our treasure Do not waste the light
Now the days are long and pleasant Do not waste the light Take these moments as a present offered up for our delight Some to save and some to savor Summer holds us in her favor Night will come when none shall labor Do not waste the light
