A good poem deserves a good reading and, I'm sorry Dylan bach, you just don't do it for me. Out of curiosity I had a root around to see what other versions I could find and it's interesting to compare the various styles.
Let's start with another iconic Welshman, Richard Burton. I'm afraid he falls into the 'very actorly' camp as well. Too much proclaiming: too little passion. Take it away, Dicky.
Mmm, let's see if that boyo from Port Talbot, Anthony Hopkins, can do any better. A brave attempt, Tony, but a little lifeless for my taste. Ever the thespian, eh? Better stick to the chianti and fava beans.
Maybe changing continents will bring a better result? Step forward, Tom O'Bedlam (a prolific reader of poetry via his Youtube nom de plume SpokenVerse). A fantastic voice and, in my opinion, a very creditable rendering of the essence of the villanelle. Full of passion and emotion, yet still spoken in the hushed tone that comes almost instinctively while in the presence of a dying light. Good but not the best I came across.
