Thanks for those links, I placed them into the body of text below the video and changed a bit of the wording so that it references you. :-)

In my proviso re: "being good" I should also elaborate this does not have to mean technically good, but more the ability to resonate musically with an audience and, more importantly, be able to communicate to them.

Also apologies to the fantabulous Matthew Ebel who's name I did not catch at the time but listening back is who I think the questioner was referring to about tipjar requests.
