the club had the right to refuse you entrance with a camera, or to ask you to not take photos when they saw you doing so, if they didn't do that they don't have a leg to stand on.
It's a frustrating situation, I had it happen with a painting of mine that someone shot an album cover in front of, even though 75% of the cover was my painting and the graphic design of the inserts used elements from the painting, they insisted that the photo was of the band.
In the end I didn't bother with a lawyer, because personally I stood to gain nothing from the situation and more likely than not I wouldn't have received any compensation even if the court ordered it. That and by the time I saw the album it had been out for a year, so the damage was already done.

Another incident was with a client of my business, who as they are still a client will remain nameless, however they took an image from a year end report we prepared for them and used it in a national business to business campaign for a sporting goods retailer. While they admitted to "making a mistake" it actually went to the stage where lawyers were involved - their argument was that because the photo was taken of an athlete they sponsor, the image was rightfully theirs, obviously it didn't hold up for very long and they ended up paying about 4 times what they would have if they had simply asked for the rights.
I don't know what I recommend in this situation, in principle I say go after them with everything you've got. It's disheartening that he didn't offer some kind of compensation or correction, even if it was simply photo credit on facebook.
Sounds like a lame club (owner).
