I'll Be Seeing You

This is another song I've been performing for over 10 years. But, not until I looked in my trusty Wikipedia, did I know the history of this song. Well, I knew it was popular in WWII, due to all the men leaving their wives/significant others. And, it was written in 1938 by Sammy Fain, and Irving Kahal. But here's the stuff I didn't know. I also didn't know the first 4 lines have a melody similar to Mahler's third. Not being an orchestral player, my knowledge of symphonies is lacking, I guess. I did know that it was played at the end of Misery, but I did not know it was played during the final episode of Beavis and Butthead, which is a TRUE work of genius.
