Great that you played Carmina Burana shortly before kick off at the Sheffield match Dubane! (not completely sure about the version though - just for your interest see the Andre Rieu version on youtube that has had over 10 million hits).
Can I make more suggestions? Regarding the music that is played in the last 15/20 minutes before Cougars emerge on to the pitch. That section is crucial. Once the music for that period is chosen, it should be exactly the same for every match. (I say that based on the success of the big brands eg Starbucks, McDonalds etc - people know exactly what they are going to get and keep coming back for more).
Working backwards from when Cougars emerge onto the pitch:
I guess you need a steward to be set up to signal to you exactly when the first Cougar player is going to emerge from the tunnel. Then you can announce It's COUGARTIME and bang on the pitch entry music just as the first player crosses the whitewash. Whatever you choose (Lets get ready to rhumble or Gangnam or Two Tribes or Land of Hope and Glory etc) stick with the same tune every match so the crowd gets an affinity with it.
The three tracks I'd have before that are:-
Last song before Cougars come out:
Your BRILLIANT version of The Final Countdown with the check-ignition-check etc overlay and the 54321.
Next to last: Carmina Burana
Before that: Vangelis 1492
Before that: selections from Top 10 and/or pitch singers.
I guess you need to work out the time needed for the last three tracks before teams come out and work backwards.
If you can get that perfected over the next few home games, I'd consider (at my own expense) (subject to directors' permission, health & safety ok etc) arranging for a brief display of Chinese professional fireworks to be ignited from the bottom corner of the ground to coincide exactly with the Cougars emerging onto the pitch.
Cheers, keep up the good work.
