/*
	Leave the sleep and let the springtime talk
	In tongues from the time before man
	Listen to a daffodil tell her tale
	Let the guest in, walk out, be the first to greet the morn
	The meadows of heaven await harvest
	The cliffs unjumped, cold waters untouched
	The elsewhere creatures yet unseen
	Finally your number came up, free fall awaits the brave
	Come
	Taste the wine, race the blind
	They will guide you from the light
	Writing noughts till the end of time
	Come
	Surf the clouds, race the dark
	It feeds from the runs undone
	Meet me where the cliff greets the sea
