There will only be one Davey Graham and only one of many other great musicians. That is all we really need.

We shouldn't be looking for young musicians to be as good as or the equal to Davey Graham. Surely, they can be themselves and unique in their own way.

All I am really saying is that as far as the good or above average musicians are concerned the bar has got much higher in recent years and there are many more players of that standard or above.

That's fairly inevitable as there are more opportunities available plus a wealth of previous experience (from many of the greats you have mentioned) from which these younger musicians can draw.
