"She came in with her parents and had a ball taping it," said Go producer David Carroll.
The show features a mix of fun music associated with gay culture, including Cher, Pet Shop Boys, Madonna and Judy Garland. It's one of an infrequent series on Go featuring guests hosts taking on unusual projects. Lister Sinclair once hosted a show about the masters of disco and Canadian Opera Company artistic director Richard Bradshaw hosted one featuring popular classics of love.
Oh trained at Montreal's National Theatre School and starred on the Canadian stage and in The Diary of Evelyn Lau before being drawn to the bright lights of Hollywood. Among her movie work, Oh had a major role in Sideways, which won a best screenplay Oscar for her former husband American filmmaker Alexander Payne.
Oh earned a Golden Globe for her role on Grey's Anatomy, where she worked with Isaiah Washington, the actor who earned a rebuke, and was eventually fired, for a slur aimed at a gay colleague.
The show will be broadcast on CBC Radio One on Saturday, June 23rd at 10.00 a.m. EDT.
