A filmed performance of U.K. indie-rock band Elbow for national AC network Radio 2 has become the most viewed music session on the BBC's interactive 'red button' and online services.

The recording took place with the BBC Concert Orchestra on Jan. 17 at Abbey Road studios in London. According to figures released by the BBC, the one-week screening -- Jan. 31 to Feb. 7 -- attracted a record-breaking audience of 959,000.

The session was screened ahead of Elbow's BRIT Awards win for best British group on Feb. 18. Their album "The Seldom Seen Kid" (Fiction/Polydor) was awarded the Nationwide Mercury Music Prize in September 2008.

Lewis Carnie, head of programmes for Radio 2, Lewis Carnie, said in a statement: "I'm delighted that so many Radio 2 listeners accessed one of the finest live performances we have ever recorded for Radio 2, the Elbow/BBC Concert Orchestra gig. The interactive element of Radio 2 is a crucial component of our output and I'd like to thank everyone involved."

"The whole experience of playing in such a historic studio with an amazing orchestra and choir was one of the best things we have ever done as a band," added Elbow singer Guy Garvey in a statement. "Along with the Mercury and the BRIT Award it is the most incredible things that have happened to us and we're really touched that so many people have enjoyed the show on the Red Button and BBC Online."
