Eve Plumb played Sandy in 'Grease' long before current role in 'Grease Live'

You may recognize Eve Plumb from a little known television show that ran for several years in the 1970s. (Her best-known catchphrase? "Marcia, Marcia, Marcia.")

Plumb's latest project is “Grease Live,” airing, well, live on FOX Jan. 31. Plumb plays Mrs. Murdoch alongside Julianne Hough and Vanessa Hudgens.

“I think it’s going to be great fun and I think that’s the key to being nervous just have fun with it, and give it what you can,” said Plumb.

This will not be the first time the actress has had a part in the famed musical.

“I did it many years ago, a small production in Hollywood and I played Sandy, and Fran Drescher produced it," Plumb said. "Her husband Peter Marc Jacobson played Danny.”

While Plumb has worked steadily since “The Brady Bunch,” she embraces fans who still look at her at ‘Jan Brady.’

“Everybody feels like they know me which is nice.  Everyone that talks to me about it is very nice and that’s great.”

And even though she hears the line, “Marcia, Marcia, Marcia” constantly, it doesn’t irk her.

“Actually that was the parody of it that came from a ‘Saturday Night Live’ sketch," she said. "So before that it wasn’t popular."

After the recent -- and still running - Snickers commercial where Jan is played by Steve Buscemi uttering the same line, it will be famous forever more.
