I only been doing this about three years.
All the people I hear who are great with the instruments they play
Seem to have at least twenty years of experience under their belts.
The majority of them are helpful and will find something kind to say after the latest disaster and are well worth listening too.
I do not however expect them to stop enjoying their evening out to wet nurse me through my trauma and if you do keep bothering someone who is initialy pleasent and helpful you may find that their attitude cools somewhat the more of their time you take up.
I have noticed that the more I play in public places the more I come to realise that the performers I look up to and admire make mistakes of their own.
I would hate to be one of those really good performers who have no time or patience with the begginers of this world who then step up to the mike and errrrrr are less than the perfection they believe themselves to be.
SOrry going of topic will bugger of now gotta singaround to go to.
