Young will close out the show, accompanied by the Fisk University Jubilee Choir, organizers said this week. The free concert, one of nine to be held simultaneously around the world to raise awareness of poverty in Africa, will be held in Barrie, just north of Toronto.
The Toronto-born musician was part of the Live Aid show in Philadelphia 10 years ago. The 59-year-old rocker has been working on a new album, a follow-up to 2003's "Greendale."
Young was treated for the aneurysm at a Manhattan hospital in late March. His vision had become blurry after attending the March 14 induction ceremonies for the Rock and Roll Hall of Fame.
Bryan Adams, Our Lady Peace and Motley Crue are among the scheduled headline acts at Canada's Live 8 concert. Dan Aykroyd and Tom Green will host the show, which will mostly feature Canadian artists, including Jann Arden, Gordon Lightfoot and The Tragically Hip.
Concerts also are scheduled Saturday in London, Moscow, Berlin, Rome, Tokyo, Philadelphia, Paris and Johannesburg, South Africa.
