You might remember it because it was very very good, or because it was bad, or because you were excited, or mildly disappointed, or because you’d had a crap day followed by three incredible hours in a magical, strobey, packed, loud, laser-filled room. And if you’re 5ft 3, you will also remember, in exacting detail, the thread count of the t-shirt belonging to the very tall man who stood in front of you.
