Whereas many Cambridge colleges celebrate May Week with a May Ball (which actually falls in June), since the early 1980s King's has instead held a June Event (an informal version of a May Ball with fancy dress) known as The King's Affair. This takes place annually on the Wednesday night of May Week (usually around 20 June), and is attended by around 1,500 students, occupying the Front Court, bar, Hall and Chapel. Past performers have included The Stranglers, Fatboy Slim, Noah and the Whale and, in 2009, Clean Bandit. There are also large student-run College parties at the end of each term known as Mingles.
