EDMONTON -- Canadian rock music legend and environmental activist Neil Young has postponed a planned benefit concert in Edmonton.

Eriel Deranger, spokeswoman for the Athabasca Chipewyan First Nation, says the delay is due to internal management issues.

No new date for the concert has been set.

The show was to have been one of several concerts to benefit the northern Alberta band which lives in the oilsands region.

The First Nation has mounted court challenges to development approvals in the region.

Young began playing the shows last year after a visit to Fort Chipewyan and the oilsands region.
