This is the moment a Sport Relief 'early morning rave' event was disrupted - by a bleary-eyed hotel guest ranting: "Turn this f**cking s**t off".
The 7am event was supposed to raise a smile from commuters and passers-by by getting them to dance in the name of charity.
But as the bass started pumping, not everyone was impressed - as a furious guest from an Ibis hotel overlooking the event stormed out in his pyjamas.
