Speaking at yesterday's unveiling, Michael Sheen reminisced about a visit by Richard Burton and Elizabeth Taylor to the village where he grew up.
"It was the same beach that I built my boyhood sandcastles and learnt to flailingly swim... it was that beach that one legendary day Richard Burton and Elizabeth Taylor descended like gods from Olympus... in a helicopter!"
"They stepped out swathed in luxurious fur coats - it was the Seventies - and walked among us for too short a time".
