Oh boy, I LOVE this song. Simple chords, catchy melody, a bunch of harmonies, what's not to like? As fans will know, this first appeared live in the mid 80s as the song "P.S.A", but then somewhat evolved into It's The End Of The World As We Know It, and never had its own life until the band reworked and resuscitated it as a single in 2003. I'm glad they did.
