Will Fly: You're a guitarist - stick to what you know.

Mmm... after singing as front man, solo and in several bands, over 45 years, I might just know a little more than you think. I don't choose to sing very much on YouTube videos, as it happens, but those videos bear little comparison to the live music I perform. Of which you know nothing.

What I do know, after reading your pearls of wisdom here, is that know-it-alls such as thee are to be avoided like the plague.
