If you have TV Land, tune in at 8:00 pm eastern every night and you can see the very first shows, dating to 1974. The character of Nellie was introduced last night; it was great seeing the characters introduced. I didn't watch the show til a few seasons later and by then Mary was going blind and the girls were looking for husbands.
Great show, great music and my goodness, the late Michael Landon never looked hotter!
