But it didn't include Jennifer Hudson, who was due to perform at the event.
Just hours before the show the 30-year-old announced she wasn't going to be taking to the stage.
The I Remember Me singer tweeted: 'To my UK fans that were coming to the mj show in wales. I will no longer be attending due to major production issues.'
She added: 'I would have thought they would have informed you all by now, so since they did not, I am. Thank u for your support.'
According to US website TMZ, Hudson was upset she wasn't given enough time for the music originally agreed to perform.
Jennifer wasn't the only no-show at the gig.
Chris Brown was denied a visa to enter the UK as a result of his criminal record and The Black Eyed Peas also pulled out of the concert.
