Some readers — reader-listeners — have asked about the music at the end of the latest Need to Know. It’s “Wedding Day at Troldhaugen,” by Grieg (Troldhaugen being his home outside Bergen). Mona Charen and I end our ’cast with a report from Norway (whose national day, or Constitution Day, was yesterday). “Wedding Day at Troldhaugen” is about as Norwegian a piece as there is.

Although many, over the years, have noticed a resemblance between it and “The March of the Royal Siamese Children” from The King and I. Bergen and Bangkok are a long way apart — about 5,500 miles.
