CARRIE UNDERWOOD is von Trapp-ed in a world she never made. Will she Edelweiss?

Carrie is toplining NBC's live broadcast of classic tuner "The Sound of Music" in 2013.

The  former "American Idol" champion and Grammy-winning country star will play Maria von Trapp in a live perf  based on the classic musical, airing holiday season next year.

Carrie has served as co-host of the Country Music Association Awards for five years and had a few small parts in flicks.

BUT by playing Maria Von Trapp she’s poised to step into the imprint of legend.

Carrie will now attempt to essay a beloved character whose popularity has transcended all media.

 The Rodgers & Hammerstein musical debuted on Broadway in 1959 and the 1965 film starring Julie Andrews directed by Robert Wise won the best picture Academy Award.

Matthew Broderick attempted a similar venue when he played “The Music Man” for TV which was not broadcast live.

It was a stinker.
