well I suppose it depends on how you view these other singers.

i was a fan of Ewan, not some of the others you mention (I can see they float the boats of all the traddies - but just lets not go there) - and yes I think it does require a thoughtful studied approach.

psychobabble - i don't think so. I asked myself where he came from and how he got to where he ended up.

Things don't arrange themselves by magic and good fortune. perhaps we would see better performances of traditional material if this were more widely realised.
