This is a nice topic to chat about.
I think it all depends on: (A) how 'private' you want the gig; (B) your hometown Gig resources; (C) building a decent, credible contact base, and (D) how organised and committed you are to the event.
A: If you make the gig a strictly private event, you run the risk of not selling tickets. Therefore, if this is your choice, you need to succesfully action promotion through forums, magazines and fan clubs etc. I would personally promote the gig on all the major Rock/Metal forums and every Saxon Website. I would then ensure some kind of exposure in your local papers and have them arrange a competition to give out free tickets (they love that kind of thing!). I would then still leave (and advertise) the option that tickets will be sold on the door if available.
B: If you're in a fair sized town or city, chances are there will be a club/venue that is accostmed to dealing with Rock gigs. Somehow, I don't think having Saxon play at a local pub is a realistic idea. If you present a well prepared plan to the owners of the club/venue, I'm sure that they will be willing to cooperate. They will be very happy to have the business, especially if you make it clear that you are willing to spearhead promotion, advertising and ticket sales. Additionally, they will be able to provide all the Health & Safety stuff that is required as well. All you have to worry about is their request of a deposit and base fee - in other words, they will want to break even if noone decides to turn up. Opposed to that, if your homeplace is a little village or a town that hasn't a hall that can fill at least a couple of hundred people (let alone have a licence to sell booze), I'd forget about it.
C: You are going to need decent contacts and have their confidence - especially with the band and their management. On a local level you will need people that are willing to advertise the gig(local media & Radio, music shops etc.) and may need people that are qualified (Security, Bar Staff etc.) or simply willing fans that are happy to hand out flyers, provide word of mouth and stuff. Another note of local interest - try and have a local band agreed to be the support act. This will increase local interest and bring more punters that, otherwise, would have not attended, therefore increasing the demad for tickets.
D: If you get all these things ticked off, it will prove to the band and their management that you are a realistic proposal and will probably be willing to negotiate a date for the event. Either way, they will take your offer very seriously and have to provide a decent reason to saying 'No'!
Kelly - I think it is a great idea if all the forum members put some cash together to arrange a proper private gig, but we all come from so many different places and stuff. If there was a local fan club (for example in my case, Gloucestershire/Midlands UK) then it could be possible, but I can't se how it is possible on such a large scale
Sorry to be a bummer on that! I would love it if the Forum could have their own, special gig!
Who knows, maybe the band's management can think of something?
