If you’ve been listening to the CBC today, you’ll know that they’re celebrating their 75th anniversary.

The one show that’s not afraid to tell you the truth about those three-quarters of a century is This Is That, who’ve done not one but two shows for the birthday. Hosts Pat Kelly and Peter Oldring bring stories about the CBC’s greatest foley artist, the men who live with all the radio towers, and the CBC’s ill-fated rebrand in the 1980s. In other words, the real dirt.

Before listening, though, maybe give my interview with Oldring a read. He talks about their approach, bringing real characters to the radio, and whether or not he and Kelly could fool my grandma.
