British Summer Time Hyde Park has confirmed on Twitter that it will honour the thousands of £2.50 ($4) tickets which went on sale this morning.
The tickets were sold in error this morning, after an internal staff offer was leaked on the internet and went viral.
Here's the tweet, which was sent in response to a query by IBTimes UK.
@EwanPalmer A leaked staff offer meant the public could purchase reduced tickets. This has now stopped. Tickets purchased remain valid.

A source at AEG Live, the festival promoter, has reiterated to IBTimes UK that the reduced tickets will be valid.
The link to the discounted tickets has now been taken down. Ticket hunters are now greeted with a message reading ''the staff offer for these shows has now sold out."
This year's festival will be graced by a host of legendary names including Neil Young and Arcade Fire. The tickets can cost a maximum of £295.
