It has been known for a while that Mr. Guest was a huge fan of the Vic and Sade radio show and though we could only surmise the reasons, perhaps now we know for a fact, why. There is a photo of Guest along with the Vic and Sade gang in existence and a famous quote (actually a short poem) from him from another patch of time, showing his admiration for the show.
In 1936-1937 (and perhaps before and after these dates) Art Van Harvey and Bernardine Flynn played husband and wife on Welcome Valley, a show starring Guest. Not much is known about the show, other than Joan Blaine was also a co-star and Guest played the editor of a newspaper, the Welcome Valley Chronicle.
It seems now the mystery of the connection of why Guest was such a big fan of the show is now solved.
