David Bowie has given a boost to upcoming Canadian band Arcade Fire, by allowing the rockers to release their recent live duet as a limited edition download.

The HEROES star joined the newcomers for a rendition of their hit WAKE UP at New York City's Fashion Rocks event in September (05).

Arcade Fire frontman WIN BUTLER says of the collaboration: "It was very special to have the opportunity, because our record only came out less than a year or so ago at the time and we were remembering playing to about 20 people in a club.

"Then there we were playing with David Bowie. It just goes to show what an unbelievable year we've had."

The track will be available for one week starting 14 November (05), via internet site iTunes. All proceeds will go to Hurricane Katrina relief charities.
