So far I really like "Friends in your head", because it focuses on the people involved with making the show, which I think is why alot of us tune in regularly. The phrase is also already a part of every show so far, pretty much.
"Creative hindsight" is another favourite. It so aptly describes the point of the show, and it works for just about any discussion about things that exist, since you can then talk about why the thing exists, why it exists in the form it does, etc. "Welcome to this weeks dose of Creative Hindsight" also flows quite well.
"Magic Beans talk" is also great, the concept is often talked about so it is an established part of the show. MBT is a good 3 letter acronym. And the slight intricacy of the name not being immediately obvious is a bonus.
