Ah, you should see Cynddylan on a tractor.
Gone the old look that yoked him to the soil,
He's a new man now, part of the machine,
His nerves of metal and his blood oil.
The opening sentence is conversational; the speaker’s “Ah” expressing, seemingly, his belief that he has some interesting gossip to impart. The single, declamatory  end-stopped  line is suitably melo-dramatic.
