On Sunday night, the world tuned in to see if this new generation of stars were truly born to hand jive on FOX's Grease: Live musical event.
In addition to the brilliant performances by Julianne Hough, Aaron Tveit, Vanessa Hudgens, Keke Palmer, and Carly Rae Jepsen, a number of recognizable faces made appearances throughout the fun, 1950s-themed evening.
You might have noticed the likes of Ana Gasteyer playing Principal McGee, Boyz II Men backing up on 'Beauty School Dropout,' and Joe Jonas and his band DNCE crooning to Rydell High. But did you notice this Brady Bunch star thrown into the mix?
The original Jan Brady, Eve Plumb, joined the Grease: Live cast to play the school's shop teacher, Mrs. Murdock, who aids Danny Zucko and the boys in modifying their hot rod car and 'Greased Lightning' their way into the hearts of their ladies.
The film role was originally played by Alice Ghostley from Bewitched and Designing Women. Luckily for Plumb, Marcia, Marcia, Marcia was nowhere to be seen so Jan could step into the spotlight. Finally!
