"Jim Carroll just has to disagree with anything anyone who can occasionally"
Rather that tsay why I agree why not concentrate on what I say Muskett ?
"He wasn't ever pitch perfect and could never have been a classical singer"
We have a very early recording of Ewan singing classically - a piece called, 'The Death of Hector' made for the BBC shortly after he joined them in the late thirties
He was good enough for it to have been broadcast
His vocal range was not limited - he made a great ob of 'The Flying Cloud' and 'The Sheffield Apprentice' without effort - both among the rangiest in the folk repertoire
I've never had a problem handling most songs I've tried (I have 300 songs on my list) - - I can no longer manage Ewan's version of 'Sheffield' so I've had to find another one
Flying Cloud was among my first big songs - five years ago I found I'd lost it so I worked on it using MacColl's voice exercises and got it back

If we ever get around to to discussing his work fully you might realise that rather than 'learning anything as a playwrite", he and Litlewood and later Newlove evolved their own technique based on Laban (sound production) and Stanislavski (a theatre technique where actors took their own experiences and emotions to inform the parts they performed rather than evolving a performance technique, which is the standard approach of formal acting
The technique can be found in an excellent little book by Stanislavsi, 'An Actor Prepares'

You're just snatching statements that you have no evidence for out of the air and getting things wuildly wrong - that's what makes arguing with you useful
