There's no doubt that the salary offered would normally (in London)be that expected by a junior marketing manager with a couple of years' experience. An experienced marketing director of a charity would expect a salary of six figures.

I know very little of what the EFDSS does, despite having been around the folk scene for 45 years, so maybe the appointment of a good marketing director would help the society to become part of the mainstream of folk music. At the salary they are offering, I suspect that it would only attract someone who is extremely dedicated to the promotion of the EFDSS's work (a good thing)or who has very little experience in marketing (not so good).
