this is a story of a mom and her five children that form a singing group. Not a bad show for the time. It was a little sad to find out that Keith, played by David Cassidy, hated the music he was forced to sing. He and Danny Bonaduce both fell on hard times after the series ended with substance abuse problems and others life problems. The shows were of your cookie cutter family comedy variety. Nothing groundbreaking or trend setting, just average and fun. Shirley Jones played the mother Shirley Partridge. Shirley had a huge movie career before this show. Susan Dey as Laurie Partridge probably had the biggest career after the show. She went on to star on such shows as L.A. Law and Emerald Point N.A.S. Just kind of a fun , guilty pleasure , kind of show.
