Punters have a right to know if they are likely to have an embarrassing or unpleasant night for their £17.50. If they then choose to take a chance that the artist might have a good night, or they simply want to go along to be supportive, that's their choice. But it's an informed one.

Venues also have a right to know if an artist is regularly turning up to gigs incapable of delivering a performance. It happens from time to time that a band turns up and is pissed, of course - we had one at our festval last year. Nothing was said at the time, but I won't re-book them and if other promoters were to ask me about the band, I'd feel duty-bound to reveal that information.

In any other profession, if you turn up pissed for work you'd get sent home, and possibly sacked. Musicians get away with it because the alternative for the venue is to cancel a gig at short notice, thereby pissing off a large number of people.

I'm not trying to be unsympathetic to Davy Graham, because it seems clear he's being exploited. But so are the audiences and the venues who have booked him.
