Arcade Fire and Celine Dion, together at last?! The critically acclaimed Canadian indie rock act and the bazillion-selling fellow Canuck pop star will both take the stage at a benefit concert in memory of Denis Blanchette, a lighting technician who was killed in a shooting during a victory party for the Parti Québécois earlier this month in Montreal, Quebec.

The Fire and Dion will also be joined by Canadian singer-songwriters Patrick Watson, Coeur De Pirate, Ian Kelly and Vincent Vallières during the concert, reports The show is set to take place Oct. 1 at Métropolis in Montreal, which also hosted the event that led to Blanchette's death.

Most of the money raised during the evening will be donated to a fund benefiting Blanchette's young daughter, with the remaining proceeds assisting David Courage, a colleague of Blanchette's who was also shot but survived.

The Sept. 4 shooting took place when a masked gunman interrupted a Quebec general election victory party for the Parti Québécois, opening fire during a speech being delivered by party leader Pauline Marois. Courage was injured in the shooting, which is being investigated as an assassination attempt on Marois.
