Lyrics:

Next day, the dawn was a brilliant fiery red
And I wandered though the weird and lurid landscape of another planet
While the vegetation which gives Mars its red appearance had taken root on Earth
As Man had succumbed to the Martians
So our land now succumbed to the Red Weed

Wherever there was a stream, the Red Weed clung and grew with frightening voraciousness
Its claw-like fronds choking the movement of the water
And then it began to creep like a slimy red animal across the land
Covering field and ditch and tree and hedgerow with living scarlet feelers
Crawling, crawling
