And some of us old ones as well

I was thinking more the whole game day experience pre, during and post.

Seven nation army was a decent shout for the intro for players

Thunderstruck or Hells Bells - AC/DC

Very different intros but, both would work.

Penrith Panthers come out to Hells Bells and sounds great.

It has a slow build up and as soon as the first bell "chimed" the crowd would know that it was game on.
