Dick I understand your point very well.

But how a singer sings and how much they give into "commercial" influences is their choice. You and I can comment upon it as is our right and they are likely to take no notice - as is their right. That is their "style".

Sure, if you want to become a "traditional style" singer then it is useful to listen to the "Voices of the People" set of Topic records if you think that would be useful. Myself I would recommend Phil Tanner. But it ain't compulsory.

Personally I can't stand people who sing with a mid-atlantic twang - but it is still their choice.
