OFOTD: That's a good question mate. In this fella's OLD band, they allowed taping, but didn't have a taping section as such. After their 1997/1998 tour, management solicited fan tapes, even. People sent them in, but nothing came of it. But, granted, that was 10 fucking years ago.
Because this gig was small, in the country, in a (I presume deconsecrated) church (!), there was no security as such. I did stealth tape it though. I always stealth tape, because it's just easier. There is currently no official taping policy, but I THINK if it was any other gig, they wouldn't give a shit. I PM'd the webmaster fella when I asked him those original questions, and said I knew someone who taped the London show, and he didn't say anything about that one at all. This one specific show seems to be the issue.
Everyone else: thanks for the responses. I just mean: I paid my ticket, I've supported this artist and bought all his stuff for 15 years, I don't really feel I 'owe' him anything. He ain't bought me a pint or anything, y'know what I mean? I'm honestly not being a cunt: I guess I'm just playing devil's advocate. Having said that, the advice about the artist becoming non-taper friendly for other tapers is an issue close to my heart and has made the decision for me.
Other opinions still welcomed, though. Thank you all.
