I've been doing a lot of research for our upcoming trip which is the first week in December. Through this wonderful forum as well as the FGTO I've found numerous websites. However, I'm still not truly able to find out where and when there will be specific Christmas music concerts. We'd love to hear some at either a church or other venue. Any help? Also, I'm wondering if anyone knows if the Noelissime Paris which will be at the Paris Expo Porte de Versailles is worth a trip. We're also interested in Christmas decorations, advent calendars, etc., etc...as well as some shopping! Thanks to all who may respond with advice.
