Another Robert Horton (Flint McCullough) fan here, he was GORGEOUS! I liked Wagon Train as a series as well, of course.
Does anyone else remember The Roaring Twenties? Set, I think, in Chicago, with Dorothy Provine as a very pretty nightclub singer/dancer, and the very handsome Rex Reason as the hero, I think he was a reporter, but not sure after all this time, it WAS in the 60s. I loved all the singing and dancing, especially the Black Bottom and the Charleston. I remember being confused over Rex Reason, he was the spitting image of Rhodes Reason who was in a series set in Africa, I think, again, not sure, I found out years later that they were brothers, they looked like twins!
I also loved A Family at War, watched every episode avidly.
My first ever adult TV series was Emergency Ward 10, my love interest though was Dr. Simon Forester, played by Frederic somebody.
