G4S song 'composed for client event'

The song G4S: Securing Your World, by US country rock singer Jon Christopher Davis, has been subject to a degree of mockery by the media over the past few days.

The company denies suggestions it is a corporate theme tune, instead insisting it was composed for a "client event at a trade fair" and later used to raise money.

G4S has been under fire since it emerged that it could not deliver enough guards for the London 2012 Olympics.

Listen to an extract from the track.
