Oprah Winfrey, Jay Leno, Carly Rae Jepsen, Goldie Hawn, Andre Aggasi—and wait, is that Dr. Phil? The group may seem like an odd bunch, but they’re among the 30-plus names expected to descend upon Vancouver on October 21 for the 30th anniversary David Foster Miracle Concert.

Presented by Parq Vancouver and organized by the David Foster Foundation—a nonprofit founded by B.C. native and Grammy award-winning producer David Foster to aid kids requiring life-saving organ transplants—the event raises money for families across Canada whose children must undergo such operations. It also boosts awareness and education about becoming a registered organ donor in North America.

Now in its sixth year, the star-studded soiree will celebrate the David Foster Foundation’s 30th anniversary in Vancouver, where performances are expected from artists such as Steven Tyler, Carly Rae Jepsen, the Tenors, and Ruben Studdard. Celebrities like Oprah Winfrey, tennis legends Steffi Graf and Andre Agassi, and Trevor Linden will also make appearances.

Tickets for the event start at $49 on Ticketmaster. Past David Foster Foundation galas have taken place in Victoria, Toronto, Calgary, and Winnipeg and have raised millions of dollars for the cause.
