The 110 has had several extremely popular halftime selections over the years, but unfortunately after one season they get mothballed and each year brings something brand new. While it's OK to try something new each year, I would like to see the most popular selections re-played each year, too. Other schools do it. Their most popular band selections become a part of their school's traditions, and alumni and friends look forward to enjoying them time and time again. A long time ago the 110 performed a halftime routine to Long Train Runnin' that was just about perfect. And in recent years, we have had both Party Rock Anthem and Gangman Style which were enormously popular. Yet it looks like we won't see these performed on the field ever again. But it's the traditional things that get people excited, not exclusively playing something new again and again.
I would encourage you to stay for the postgame show, if you're looking for classics. The band does the same set of songs after every game--what we call the "standards". Long Train Runnin' is included in that show. Those songs also get played throughout the game as time allows. As we all know, promos can take away valuable time.
I don't mean this the wrong way, but you will never Party Rock or Gangnam Style performed again anytime soon. It's just the way the leadership prefers to write their shows. Some charts get replayed every 5-7 years, depending on what kind of show they want to write.
The band has built it's reputation on playing new music mixed with classics. That IS the tradition of the 110. That will not likely change, as it's proven to be what the majority of fans like (majority, not all), and it helps recruit kids to come to OU to be in the band. You'd be surprised to see just how many high school programs emulate the 110 and utilize 110 students on their band camp staffs each year. It's far more than the bands that show up for band day.
Just some food for thought.
