While flipping through the channels, I saw Betty White on my local PBS station. It was a late 50s series called "A Date With the Angels". Apparently WHYY was showing old Christmas episodes of shows like Dragnet and Ozzie and Harriet.
Left intact in the shows was a series of ads for Plymouth and their 1957 Money-Ahead Contest. The on-air presenter for that was a young Tom Kennedy. I suspected it was him, but he confirmed it by identifying himself as the announcer during the end credits.
Anyone else see this? I suspect this was a package available to PBS stations, so you might want to be on the lookout for this. (The show wasn't that good, but it's an interesting look at what else was on the tube opposite Lucy and Uncle Miltie)
