You make interesting points John, thank you, but I can't agree with you on a few things.

I grew up in the 60s in Liverpool, but I don't sing like Cilla Black...
I heard Jim being interviewed on Front Row, so I heard him speak as well as sing, which is why I made this point. His singing style is quite different from his speaking voice.

I'm not 'having a go' at Jim, I wish him well in what he's doing, but it could be so much better.
