Rockers The Strokes, Arcade Fire and Bon Iver are to form a supergroup for a one-off performance on Saturday (20Sep14).

The Strokes bassist Nikolai Fraiture and Bon Iver frontman Justin Vernon will join brothers Win and Will Butler from Arcade Fire for the show in Montreal, Canada.

Styling themselves as the Pop All Star Band, they are expected to perform a short set during the halftime break at the Pop vs Jock Iii charity basketball game, which is staged as part of the Pop Montreal festival.

The rockers are also set to show off their sporting skills by taking part in the match against a local team, according to
