I sort of agree with Michael. Market economics should dictate that the singer sets his/her fee for the event, and the organiser sets what price he/she sells tickets at. I would and have paid £10 to see Vin and don't see this as an attack on him. But maybe there is a difference between saying "I think I am worth £10 a ticket" and saying "I won't come if the entrance fee is less than ....". I have heard other artists set a minimum fee in this way though and don't quite understand the reasons. Surely it can't be that the artist feels they are being sold short, as their fee for the night is unaffected. Is it something to do with standardizing prices - punters could see a person for £10 at one event and £5 at another? But surely this just reflects capacities of venues, amounts clubs are willing to subsidize, fee structures for belonging to clubs and so on? I just don't see the reasons why an artist would want to set a minimum ticket price. Please enlighten me.
