This appears to be the only address I can find for the band which I find odd as I assumed they would have a British management address. I intend on writing to them too. I send things off to the states to be signed quite abit (I'm also in the UK). For an international SAE for US to UK you would need something called 'Forever Stamps'. Unfortunately they arnt cheap to buy online (lucky for me my mum lives in the US and sends them to me). You can find them on ebay if it's something you wish to persue. Hope this helps.
