If you choose to join the mailing list I'll collect your email address. This isn't so I can sell your details to the highest bidder so they can constantly remind you how poor you are in bed and how much fuller your life could be if you buy their Viagra and fake Rolex watches, it's so I can send you emails updating you with the latest news, gig details and anything else I think you might be interested in.
The mails won't be sent out at regular intervals, they'll be sent out whenever I've got some news I think you might be interested in. If at any time I start getting on your nerves you can unsubscribe by sending a blank email to firstname.lastname@example.org. Details of how to unsubscribe are included in every mail sent out.
If you're contacting me through the contact form and you include your email address, I may use it to reply. That's it. Your email won't go any further than me. There... I told you I was responsible.
