"The Sound of Music" is one of Ellie's favorite movies, and we listen to the soundtrack in the car all the time. We've never heard it playing in a train station before, though.
We so often went to Antwerp when we were living in The Hague. Wish we'd been there on this day! Thank you, Grandpa, for sharing this wonderful clip!
For those of you wanting to know the "why" behind the happy, this was done to draw attention to a talent competition in Belgium called "Op Zoek Naar Maria" (roughly "On the look-out/search for Maria"). The winner of the competition would play the role of Maria von Trapp in the revival of "The Sound of Music" at the Efteling Theater (info courtesy of wikipedia).
