Best insider tip for Talen Energy Stadium ?

One insider tip I got from the “Sons of Ben” is that I needed to know the song to sing when the Union scored a goal.  He then went into a chant that goes: “DOOP DOOP DOOP da da DOOP DOOP DOOP da DOOP DOOP DOOP da da DOOP DOOP DOOP”  You should also get in on this when you attend a game so that you truly feel like a “Son of Ben” Franklin.
