Arcadian Dream

You are in a mall when the zombies attack. You have:
1. one weapon.
2. one song blasting on the speakers.
3. one famous person to fight alongside you.

Weapon can be real or fictional, you may assume endless ammo if applicable. Person can be real or fictional.

1. A cricket bat.
2. 'Bulls on Parade' - Rage Against the Machine
3. Chris Keller (Oz) - I get the feeling this is a situation in which a homocidal sociopath would have the advantage ;)
