The iconic love story is a real story, and I had a chance to chat with a member of the von Trapp family who tells me their special connection to Philadelphia.
"I think our story is even more relevant again today," says Kristina von Trapp, the granddaughter of Captain Georg and Maria von Trapp. "It's a story of hope and love, where good triumphs over evil."
Their story inspired the Broadway musical "The Sound of Music" in 1959.
It was then turned into and Oscar winning film in 1965, starring the legendary Julie Andrews as Maria.
"Every time I watch it, I get sucked in," says Kristina. "It's amazing. Listen, I know how it's going to end, but every time I see it, it's always pretty special."
The von Trapp family famously fled Austria and landed in Vermont, where they've run the von Trapp Family Lodge & Resort since 1942.
"They found this hillside and it was reminiscent of Austria," says Kristina.
But many don't know they settled in Philadelphia first.
"My dad, Johannes, was born there on January 17, 1939," says Kristina.
The musical returns to Philadelphia this week.
Cayleigh Capaldi plays Maria in the new touring production.
"It is a gift that keeps on giving every night," says Capaldi. "Just when I think I have her figured out, she continues to surprise me."
Many might find this fact about the real Maria to be even more surprising.
"She was pretty firm and stern," says Kristina. "She had to be. She kept everybody together and singing around the world for 20 years, which was pretty incredible."
And the captain?
"He was a little more warm and kind than you saw in the movie," says Kristina.
Fun fact: there were actually TEN children.
"There were the original seven children, like you see," says Kristina. "And then Maria and the Captain had three children together. Also, the oldest was a boy, not a girl."
Kristina also likes to note: "Edelweiss is not the Austrian National Anthem."
But one thing will always remain true: this story of love and courage and family is timeless.
"It is so important for us now to preserve the original source material so that people can continue to fall in love with it," says Capaldi.
The Sound of Music is on stage at the Academy of Music March 31 - April. 5
