Here's a quote from CBC announcer Cy Strange, excerpted from Signing On by Bill McNeil and Morris Wolfe.

"I was the announcer on Lucy Linton's Stories From Life, and I was known as Sunny. The reason was that the sponsor was Sunlight soap. The thing necessary for that stint was boyish enthusiasm as all the commercials were done in Aunt Lucy's kitchen in a typical small town. Sunny Rogers, the boy next door, was always in and out, looking for some of her cakes and cookies. It was simple-minded, but we sold Sunlight soap like you wouldn't believe."
