Applegate, Uncle Martin, Boothby, Judge Bone - an impressive collection of characters.

This is my last chance to ask a question that has bothered me for many years, so I'll ask it here. Many years ago, on one of Boston's classical radio stations (WCRB), I would regularly hear ads for the Ray Walston Fan Club. "Help boost Ray's career." This was well after My Favorite Martian went off the air, but long before Picket Fences. I always wondered why a fan club was advertising for members, why they were doing it on a classical radio station, and in what way they intended to boost Ray's career. I suppose I'll never know, but does anyone have any ideas?
