A bit of history on the song: though it has long been associated with WWI (and I am sure ALL of you remember that war!), it was actually written to be sung at a fraternity banquet the year before the war was declared - in 1913, by a pair of Yale undergrads. I tried to find a decent audio file of the song for those who don't know it, but most of them were not great quality...I have included one of them at the end, if you want to listen.
There's a long, long trail a-winding
That long, long trail with you.
There's a Long, Long Trail.
Thursday Theme Song.
