"Mee MEEmee MEEE-mee" = Beaker singing the "Nine ladies dancing" stanza of "The Twelve Days of Christmas"
Ah yes, the immortal words of Muppets... heh-heh.
One of my favorite Christmas albums from childhood is John Denver and the Muppets: A Christmas Together. Kermit is there in all his sincere, well-meaning green-frogness. Miss Piggy is her bossy diva self (gee, remind you of anyone?). Animal protests his "won't go! won't go!" unless figgy (not "piggy") pudding is produced forthwith. The two grumpy guys are...well, grumpy. Everyone is there; and they chime in happily on "Deck the Halls," "The Twelve Days of Christmas," and "Christmas Is Coming." The Muppets do a sweet-spirited performance of "Stille Nacht," in German, after which John tells the story behind the beloved carol. Then the entire group sings the song in English.
The only thing missing from the album is a good solo by the Swedish Chef warbling some buried treasure of a European Christmas carol that only Swedes would recognize. I'm not sure how he could top his "hurdy-gurdy, get duh squirrelee"* act or his unique rendition of "Blue Danube Waltz" (ie. "Da, da, da, DA, BORK, BORK, bork, bork"), but the Chef would be up to the challenge.
* Yep, everything...somehow relates back to squirrels.
