The von Trapps singing Edelweiss (great grandchildren) 

Here’s a link to the album where The von Trapps recorded Edelweiss with Charmain Carr (Liesl in the Sound of Music) pinkmartini.com...
The von Trapps are currently pursuing individual careers outside of music, but they continue to make special guest appearances with friends and artists such as Pink Martini.
This performance was shot in 2013. They were working on an album with Jack Hanna (who evidently is a 5 star yodeler) and they sang for our staff out of the goodness of their hearts. As you can see, this is breathtaking.
Thank You , von Trapps!
