Mary Roos
From Muppet Wiki
Mary Roos (b. 1949) is a German recording artist who appeared in a specially filmed insert for Die Muppet Show which was a re-edited version of Episode 121 of The Muppet Show.
As part of a deal for German distribution of The Muppet Show, the Mary Roos spot replaced Twiggy singing "In My Life" with "Komm Zu Mir" (in English "Lean On Me").
She sang with two female Whatnot Muppets and Janice. Zoot played sax, Janice plucked the guitar, Animal on drums, Rowlf on piano (and with dubbed lines), and for the first and last time Floyd on the bongos.
