First thing that you'd suspect is that the brewery doesn't want folkies because they are rough types who make a lot of noise ......

Thinking about that - I remember when folk clubs were the province of bearded types in Arran Sweaters who fancied themselves as Trotskyites but had failed the medical for the Young Socialists.
The male folkies were even worse.

Nope - there' sthe danger that the rep's corporate image centres around

a) girls who consume their own weight in Breezers over a three hour session
b) their lager tank boyfriends
c) indie bands Fridays and Saturdays, Karioke Sundays
d) Champions League (full volume) on other nights.

This will not sit well with the rep's fear of being tainted with nerdy old farts croaking out ballads and playing wheezy accordions.
(If it helps, I'll stay away .. )

Whats needed is a good bit of folk marketing - to disabuse the brewery of their preconceptions ....
