What is the oldest series where most all the principal actors are still alive?

My vote is The Dick Van Dyke Show. Morey Amsterdam, Richard Deacon and Jerry Paris are the ones who passed away. Van Dyke, Tyler Moore, Reiner, and Rose Marie are still here over 50 years later.

I mentioned this before but there is one series from the 60's in which all of the primary cast (5) are still living. I can think of no other series from that time or earlier that holds this distinction.

Can you name it?

I don't know if this is the one you're talking about because it had 6 main cast members but it looks like the whole cast of Please Don't Eat the Daisies is still alive.

My "vote" goes to the late '50s version of Lassie, with Jon Provost as Timmy. Jon is still with us as are all 4 actors who played his parents at times (Cloris Leachman, Jon Shepodd, June Lockhart, and Hugh Reilly).

I thought I put 6 but you're correct on both counts.
