Led Zeppelin has been my favorite band for as long as I can remember. That said, spending seven hours doing nothing but listening to them might have been a little much. I knew the end was going to suck but I didn't realize how badly it was going to suck. I knew Coda was going to be bad but I had forgotten just how pedestrian it is. And the second disc of Physical Graffiti...ouch. Except for Trampled Underfoot and Ten Years Gone that album is a total waste. There was discussion about starting from the end and working backwards to Led Zeppelin I but I figured everyone would be too drunk and tired to notice how good it was. We tried to make the end better by replaying Led Zeppelin II and III but I think by that point everyone wanted to go home. So when you're trying to come up with a creative theme party that's based around a musical group I'd pick one with a less extensive catalog...like Kelly Clarkson.
