The end credits sequence for Muppet Treasures is online.
Recently somebody made a fake end credits sequence that I linked to recently, but I am a little disappointed that one of the "attic videos" does not end with a regular version of the closing theme, instead being an instrumental version of "There's No Business Like Show Business". It's still a good rendition, though, and maybe it is better for the end credits to be more quiet when there's no mayhem happening during the credits (no Animal messing up the attic, no constant explosions, no characters tossing bombs to each other, no Kermit and Fozzie arguing over whether to throw out a bottle).
I also found an upload of the end credits for a Spanish version, which uses a different font, and yet even though it's apparently Spanish, the credits are in English. Also, the credits don't list performers or guest stars. Weird.
