lol, that's not Irish at all if you're talking about what I think you are.
It's the song "Thunderstruck" by AC/DC. The intro video is absolutely badass. Almost too badass for this team.
I kind of wish they'd use a different song, though, since I believe that one is or has been used by the White Sox.
Nah hes not talking about that although his description made it seem that way.
Its just some random song they played before thunderstruck when the players were going back to the dugouts
