One of the UK's biggest festivals have told their artists not to swear
We're not quite sure how this is going to go down.
Wireless Festival have asked artists performing at the event not to swear, and not to wear "offensive" clothes.
The festival takes place in Fisbury Park every summer, and has received a number of complaints recently.
The Friends of Finsbury Park have complained about noise levels, drug taking and anti-social behaviour at the festival.
Haringey Council decided not to revoke the licence totally, but instead included new conditions that "request that performers do not sing or play any vulgar, obscene or banned songs or carry out indecent acts, or make any vulgar gestures, actions or remarks during the performance".
It also says that performers must "not offend the general public" and gives examples like "attire which expose the groin, private parts, buttock or female breasts".
We can't picture that going down too well with the artists.
The festival will also end 30 minutes earlier than it normally would.
According to BBC, The Friends of Finsbury Park were happy to see a few of their requests upheld, but weren't happy that some of their other requests were disregarded.
Their statement read: "Several of our proposed licensing conditions have been disregarded by the committee, of which the most important is our request to reduce the number of attendees at the event."
