I’d never heard he had the surgery. The results of such surgery can be hit or miss.
Some of the live recordings of Plant circa 68/69 are amazing. He had a sound like no one else.
And I'm sure that's how Plant wants people to remember him, instead of a 60+ year old man singing "Squeeze my lemon until the juice runs down my leg."
“He had a sound like no one else.”
Yeah. Like a hysterical shrew or a castrato.
That’s true, although he had some close imitators, e.g. John Lawton (Lucifer’s Friend, Uriah Heep).
