Voiceover, Dialog, Spoken Text, Script, or Lyrics
(Lyrics) There's a humming in the restless summer air
And we're slipping off the course that we prepared
But in all chaos there is calculation
Dropping glasses just to hear them break
Oh, oh you can try and take us
Oh, oh But we're the gladiators
Oh, oh You can try and take us
Oh, oh But victory's contagious
Coming in February
