The Real McCoys (1957–1963)

Re: the other comments. But although Walter Brennan was great as grandpa DO NOT forget the rest of the cast. Richard Crenna was wonderful as Luke, and Kathy Nolan (as she was called in the first years of the show, not Kathleen) was fine too, among others. She eventually left the show in a bitter contract dispute for a short-running series (check her credits) and her career went the route of DAvid Caruso from NYPD BLUE. This show had a wonderful theme song: "Want you to meet the family known as the real McCoys. That's grandpappy Amos, they head of the clan, he roars like a lion but he's gentle as a lamb. And now here's Luke who beams with joy since he may take Mrs Kate McCoy". A good show that never recovered from Nolan leaving - Luke as a widow didn't cut it.
