Today's blog announced the 40 for 40 It's a Living marathon that will be airing on Labor Day, 40 episodes starting at 5AM eastern time. Assuming Johnny Carson gets his usual hour, that means the It's a Living marathon goes thru 2AM. Blog says it is for the 40th anniversary, but it is actually the 42nd anniversary this year. 40th anniversary of first being cancelled though.

I'm asking Pavan for clarification on this one. He put September 7 in the original post, but Labor Day is on September 5 this year. He may have used the information from 2020.

They did the 40 for 40 It's a Living Marathon in 2020.

I removed the post. I don't think it's happening. He said he saw it on their social media, but it must have been from 2020.
