Thousands, Jon, thousands.

Talent is no pre-requisite of success. Granted, having said that, none of the people here mentioned are slouches, by any manner of means. But my line has twinges of the theme of the Pro vs Am discussion elsewhere.

We, as 'professional' musicians (and I don't put myself in ANY category - certainly not among any names mentioned here), have to always be aware that "There's kids out there who can whip the frets off you".

Being 'discovered' is what makes the difference.
And a lot of that depends on luck.
