Blur unveiled two new tracks last night (02.07.12).

The 'Song 2' band performed 'Under the Westway' and 'The Puritan' from a rooftop at a secret location via a live video stream, watched by fans around the world.

The band last staged a reunion show in 2009 but are back together again for a special show on August 12 in London, to mark the end of the Olympics.

Bass player Alex James said the band had only started recording the tracks three weeks ago, and finished 'The Puritan' last week.

When asked whether there was a future for the band after the Olympic shows, Alex told BBC Radio 1: ''I've got no idea what happens next, or if it ever happens again.''

However, he did add: ''There's never been a period where more than six months have gone by and we haven't stuck our heads in and had a bish-bash. It's just really, really good fun.''

When asked how well the band - which includes singer Damon Albarn, guitarist Graham Coxon and drummer Dave Rowntree - have been getting on, Alex added: ''We click back into it like a family at Christmas. We're not having fist fights any more, but I sort of miss that!''

Both 'Under the Westway' and 'The Puritan' will be released on vinyl and for download on August 7.
