Here's a little selection of the lyrics:
You love your job and the people too / Making a difference is what you do / But consider all you have at stake / The time is now don't make a mistake
Because the enemy prowls, wanting to attack / But we're on the wall, we've got your back / So get out front and take the lead / And be the winner you were born to be
G4S! protecting the world / G4S! so dreams can unfurl / 24/7 every night and day / A warrior stands ready so don't be afraid
G4S! secure in your world / G4S! let your dreams unfurl
We're guarding you with all our might / Keeping watch throughout the night...
