The song was made available on Friday on various sites. Aldean's representative says all proceeds will be donated to the Direct Impact Fund dedicated to victims of the tragedy.

Aldean was performing at the Route 91 Harvest Festival on Oct. 2 when a gunman fired on the crowd from a hotel room, killing 58people. Hundreds more were injured.
