Nostalgia and the memories are definitely a big factor, and I have definitely had a pretty good share of them. Bill & Ted is one of our favorite things about HHN and it is always fun speculating on what they will target next year. I get excited everytime one of the songs comes on the radio (My Songs Know What You Did in the Dark just came on!!!! *Metal Fist* *Metal Fist*)
The biggest thing I miss is when the videos of past B&T were replaced with Stupid Human Tricks videos. The old videos brought so many memories back it made the show much much better, things like Demon Babies, Obama vs McCain, The Twins, so many great things... it really helped build the camaraderie of the fans and also helped amp everyone up. Without it the crowd isn't as pumped and as a result it is nearly impossible to start a wave anymore.
