No I don't know why you can't name names and I don't know why you can't break cover and I have no idea who you are talking about.

There was always a folk "industry". It and folk have changed.

I can think of loads of people who have long involved catering riders indeed I have booked artists with them. Some have dietary needs, I have been asked for specific brands of soya milk for example.
Richard Thompson has particular needs away from the ordinary. Some have agents who write them.

I know people in the music industry who have this sort of rider. Most folk people I know have no rider at all.

I can thing of one band who went through a day with nothing to eat or drink whilst they were faffed about from arsehole to breakfast time by a bunch of knobheads who believed bands didn't need to eat.
