Actually, I'd heard part and parcel of this story before -- I can't remember when or where -- about the legendary 'party' at Eric Idle's place, but I hadn't read all of it (as apparently was shared by the late Fisher before her passing). Isn't it fascinating what a little harmless get-together (ahem) can do for one's attitude? Stranger things have happened, indeed.
As always, thanks for reading ... and live long and prosper!
