It's sad that Astrid is gone as she was a wonderful woman, not just a good author. I'm proud to be from Sweden when she's mentioned. She has really put Sweden on the map, it seems. Her books were spread all over the world. She also wrote texts to songs (Pippi Longstocking, but also others) and some of them are really loved by us. I'll try to find out if some of them is translated...
The most loved and sung song is "Ida's summer song". Here's a midi: Idas sommarvisa. Unfortunately the text on the site is in Swedish. Have somebody heard this melody? The song is from another of her books, "Emil in Lönneberga"; Emil was a mischievous boy who made his father crazy, but also a very kind child at times!
By the way, Tears for Bears have recorded Pippi Langstrumpf (Live)
I like their recording even if they've made some changes...
