The idea about the Bob Dylan song about New York got me looking at Dylan's songs and I came across his song called "Talkin' World War III Blues". The lyrics can be found at the site - http://orad.dent.kyushu-u.ac.jp/dylan/talkwar3.html

Since you will hear many people talking about WW3 after this tragic day and what's going to happen,etc. I thought this song lends itself to discussion around this day.

You can give the kids a copy of the song, read and discuss it and connect it to our present world situation.
