Blur have revealed they are debuting two new singles on Twitter ahead of their Olympic closing ceremony gig.

The reunited quartet – Damon Albarn, Alex James, Graham Coxon and Dave Rowntree – will perform the songs called Under The Westway and The Puritan in a live video stream via their Twitter page on July 2.

The band have written the tracks for their set at the BT London Live Olympic closing ceremony concert on August 12 in Hyde Park, where they will play alongside the likes of New Order and The Specials.

Frontman Albarn said, "I wrote these songs for Hyde Park and I'm really excited about getting out there and playing them for people."

The live stream takes place on Twitter at 6.15pm on July 2 at @blurofficial. There will also be an interview with the band.

The tracks will be available later for download and a limited edition seven-inch single will be released by Parlophone on August 6.

The Britpop legends, who received the outstanding contribution prize at this year’s Brit Awards, are playing a handful of dates in August in the run-up to their Hyde Park gig – at Margate Winter Gardens, Wolverhampton Civic Hall and Plymouth Pavilions.

But fans hoping the reunion will last long enough for the band to produce another album could be disappointed. Albarn has said that the closing ceremony performance could be their last.

He told Metro last month: "I don’t know how we’ll feel when we play Hyde Park. Some days I feel one way and other days I feel the other.

"If you don’t see something as a career but as an important part of your life, you don’t know how you’re going to feel about it.

"We want to put on a great performance but nothing’s been said between us about the beginning or the end."
