ABC to Air Primetime Special THE UNTOLD STORY OF THE SOUND OF MUSIC, 3/18

On this morning's Good Morning America, it was revealed that ABC will air the primetime special THE UNTOLD STORY OF THE SOUND OF MUSIC on March 18 at 10 p.m.

Julie Andrews appeared on this morning's broadcast and shared with Robin Roberts stories of recently revisiting many of the film's memories as she travelled with Diane Sawyer to retrace specific scenes and locations. Watch the appearance below!

"The two of us went back to Austria and we visited the scenes of 'The Sounds of Music,'" Sawyer said on "GMA." "You'll hear the hilarious things that happened there, you'll hear what she was really thinking as she was walking toward Christopher Plummer, I find your mountain and of course 'Do-Re-Mi.'" She added, "We never stopped giggling and laughing and talking."

The two women will also visit the real von Trapp home, which was the first time Andrews ever saw the actual estate in person. For the movie, she explained, they created a "slightly bigger house in a more countrified setting."

Sawyer's special, "The Untold Story of 'The Sound of Music,'" airs March 18 at 10 p.m. on ABC.
