You're kinda in luck: next year there's a not-musical stage show produced by Cleese being released. The backstory is pretty contentious though, Idle and Palin have completely disowned it via Twitter for various reasons, not the least being Cleese politicizing it with changes to the Loretta scene and removing the closing "Always look on the bright side of life."

(I don't use Twitter but the war between Cheese vs Idle/Palin is there)

A relaunch is dare possible only because it's about that one in the Big Religions (tm), not the other one.
