Murray, I have heard that the TV stations will, for the most part, be running specials that honor the victims, the heroes (especially), etc., and focus on hope for the future, rather than a day of mourning. A main reason that the idea of making it an official holiday was that people then to use these mainly for picnics and drinking beer.I believe a period of silence is planned, for all the TV and radio stations, at the time of day when the second tower collapsed.
Probably some of you folks have more details.
If I have gigs (at retirement homes) booked for that day, I will include at least a few songs comemorating that day, and a few optimistic "patriotic" songs.
