As an amateur (mostly), it has always been appreciated by me that the professional guest at the clubs has been approachable, not least for advice.

Those that I remember pestering (over a period of 30 years) include Nic Jones, Martin Carthy, Tony Hall, Tony Rose, Maddy Prior, Dis Disley, John Foreman, Alistair Anderson, Dave & Toni Arthur, and probably many others too. And I do not remember anyone who has ever (appeared to) resent this. Polite and helpful, all of them.

(Harvey, I have only seen you once, in concert in Swansea, somewhere about 1972? But I can't remember much about the night.)
