The Greenbelt Harvest Picnic has traded one Canadian music icon for another. Gordon Lightfoot is taking Neil Young's recently vacated spot in the festival.

"We are very excited by the addition of Mr. Lightfoot and will be making more announcements in the coming days," said Jean-Paul Gauthier, the festival's producer in a press release.

Lightfoot, now 74, helped shape the sound of popular folk in the 60s and 70s with songs like Sundown, If You Could Read My Mind, and The Wreck of The Edmund Fitzgerald.

He was brought in to replace Young after Crazy Horse's guitarist Frank Sampedro injured his hand. The band has cancelled the North American leg of its current tour, including a headlining spot at the Ottawa Folk Festival.

Many have bemoaned the fact that they bought tickets to the picnic just to see Young and Crazy Horse. The organizers have offered a partial discount to ticketholders after the band pulled out of the show.

Organizers are offering a $40 refund. The new ticket price is $99.50.

"Ticket buyers who purchased through TicketMaster will be contacted by TicketMaster," Gauthier said. "Ticket buyers who purchased from consignment locations, can pick up their refund beginning Saturday Aug. 24 at 10 a.m."

"All buyers must bring photo ID, their tickets and the original debit or credit card used to receive their partial refund."

The Greenbelt Harvest Picnic is scheduled for Aug. 31 at the Christie Lake Conservation Area in Dundas.

This year's show features performances by Daniel Lanois, Emmylou Harris, the Arkells, Pegi Young and the Survivors, Trixie Whitley, Rocco DeLuca, Harlan Pepper, Whitehorse and Basia Bulat.
