This Halloween, “Aargh!” becomes “Arr!” as the pirates take over. A boatload of them will be swashbuckling down the Thames and if you’ve got any sense you’ll join them. The Dutch vessel leading the raid will be manned by Andy P who'll be throwing down huge beats with the odd horror sample thrown in. Slip into your best pirate attire and prepare to terrorise the seven seas – or the Thames at least, which is close enough. Over 18s only. Dress code: fancy dress/smart.
