To say I was floored when I heard this "reunion" announced is a true understatement. As much of a control freak as Waters was near the end of Floyd, it just wasn't Floyd without him. I didn't get into the stuff either he or Gilmour/Mason/Wright did on their own post-TFC (I found TPACOH rather masturbatory and the two "Floyd" albums were like soft-rock easy listening for the most part), but all you need to do is put on DSOTM, WYWH, Animals, or (the greatest album of all time) The Wall and it erases everything after TFC from your memory.
While I don't think this will be a permanent reunion or even a harbinger of a tour with the 70's lineup, it will be nice to see/hear the four of them on stage together again, and it's for a wonderful cause, which makes it even better. Is the show going to be broadcast this time around, or is MTV doing yet another "Real World/Road Rules Talentless Reality Whores" marathon that day instead?
