I used to love for my late wife to play “Edelvweiss” on the piano and sing.
Here's a song about the edelweiss, but it's a safe bet that it's not the one she liked to play and sing:
Adolf Hitler's Lieblingsblume ist das schlichte Edelweiß (Adolf Hitler's favorite flower is the simple edelweiss)--Harry Steier (1934)
A charming memory to be sure (and one which I share with my wife). Which reminds me - I need to get the piano tuned.
