Never thought I'd see this...

Sony Press Release by way of Digitally Obsessed

The set includes a bonus featurette entitled "Weemawee Yearbook Memories," which the press release claims has interviews with the main cast, including Merritt Butrick. Usually these types of featurettes have current interviews. Since Butrick, who passed away nearly twenty years ago, is included, I'm assuming this will be some kind of combination of archival and new interviews.

Still waiting to hear if the music got cleared.
