The cast was very musically oriented!
Music to our ears – the four Cartwright actors would end up singing on the 1964 album, ‘Christmas at the Ponderosa’. Lorne Greene turned out to be the most successful singer of the group.
Pernell Roberts hated the show.
Roberts played Adam Cartwright, the eldest Cartwright son. Apparently Roberts hated the show and called it demeaning to women, glorifying of wealth, and low brow in terms of humor. He even pushed for script changes but eventually left the show instead.
