Radio One's Big Weekend: Thousands gather for last day of festival
Thousands of eager pop fans are soaking up the last rays of sun as Radio One's Big Weekend comes to a close in Derry.
Artists including 30 Seconds to Mars and Paramore have already taken to the stage on the third and final day of the festival.
Olly Murs is also celebrating after selling 1.2 million copies in the United States of his chart topping single Troublemaker.
The Essex pop star told the crowds today it was a major success for him as a new artist.
"I just sold 1.2 million from Troublemaker in the USA, that was a big thing for me as a new artist (after) all the success in the UK, to go to America and to sell a single 1.2 million (times)..is a massive achievement for me," he said.
Other acts at the final day of the three-day event included Dublin rockers The Script.
Band member Mark Sheehan said he was delighted to be back.
"We are so used to it raining that when the sun finally shines we are just waiting for it to rain again, when we think people are going to walk out," he said.
He admitted the band still experienced nerves.
"We have got to learn to channel it in a positive way. The day you lose that edge is when you are in trouble," he added.
Sheehan said the vibes in Derry were brilliant and the Big Weekend was a great opportunity to attract massive live acts who usually focus on London.
"The amount of money it is generating for the local area, kids out there seeing their first big concert for free, it is incredible."
Girl band Little Mix were among other performers today.
On Friday artists including A$AP Rocky and Dizzee Rascal took to the stage as the three-day event began in Derry's Ebrington Square.
But to add to the already heaving line-up of pop acts, Robbie Williams joined Dizzee on stage - much to the delight of the some 12,000 fans that turned up.
A host of acts soon followed the big-name surprise guest, with Katy B taking to the 1Xtra Arena this evening among others.
Disruptions at Heathrow airport on Friday due to an emergency landing forced several artists to pull out of the show.
A statement from the Radio One press office said:
"Unfortunately due to the travel disruption affecting Heathrow we've had to cancel a few performances but we've still got an exciting line-up for our audiences."
And despite the rain, Saturday Scottish rockers Biffy Clyro took to the main stage along with a host of other acts including the Saturdays.
Bruno Mars will complete the three-day festival this evening.
