I certainly remember this show, especially the first episode. Cameron Brooks has just arrived in Millsburg. In a flashback, we see him as a young man when he was preparing to leave that town many years before. He is with a young girl named "Tina" and is telling her good-bye. They promise that when he returns to Millsburg, they will kiss. Back to the present, Brooks is seen meeting the townspeople. One of these is a woman named Chris Logan. As this episode moves toward its conclusion, it is seen that this woman is actually the "Tina" he said good-bye to (full-name Christina). He reminds her of the promise from years earlier that they will kiss. She remarks it was a promise made many years before. He notes that "promises were meant to be kept" and they do kiss. I thought it was a beautiful way to begin the TV series. Chris, played by Constance Moore, was a regular in the show.
Persons should remember that Robert Young had recently finished being in Father Knows Best (1954-1960) when he began this series. In fact, Father Knows Best continued on in prime time for two seasons (1960-61, 1961-62) on CBS. As such, Young was actually being seen in two separate shows in prime time during that 1961-62 TV season. Window on Main Street was on Mondays and Father Knows Best was on Wednesdays. Maybe the plot was too similar for the new series to take hold. Window was trying to solve the concerns of someone from the town in 30 minutes just as Father had tried to do with a family member or friend during its long run.
It's a series few remember or know of, but I do; particularly that opening episode.
