Imagine a space-themed night of incredible live music and musicians, then consider that same night at a leg-wobbling 80 metres high with panoramic views of up to 20 miles across London. Nice? Thought so. The 2012 Olympic structure is pretty iconic, as should be your out-of-this-world experience as the sun sets to the soundtrack of breathy harmonies from Astronauts, Transept and Paddy Steer. There'll even be freshly cooked snacks available, making sure to stimulate every one of your senses. Over 18s only. Valid ID required.
