Depends on WHATEVER inspires you and in whatever situation!
Okie dokie, fighting songs then for when we get to play counter-revolutionary and stomp lefties into the dirt:
Lets start with AC/DC: Back in Black, If You Want Blood You've Got It, Thunderstruck. Then some Judas Priest: You've Got Another Thing Coming, Riding On The Wind, Defenders Of The Faith, Living After Midnight, Breaking The Law. Add some Iron Maiden: The Number of The Beast, Killers, Murder In The Rue Morgue. Now throw in a few bottles of Jack Daniels to fire every one up, and I'd say we're set to clear out whatever public parks the unwashed hippies wish to occupy!
