London 2012 Olympics: Games security firm G4S release cringeworthy corporate power ballad The lyrics continue: "'Cause 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." Next comes the stirring chorus: "Calling G4S, protecting the World / G4S, so your dreams can unfurl / 24/7 every night and day / Our warriors stand ready so don't be afraid." If G4S were as good at securing the Olympic Games as they are at power ballads then London will have nothing to worry about over the next month. In light of recent events, however, that appears to be a big if. Indeed, the warriors don't seem to be ready to stand.
