I think fans make a big difference:
The home fans especially in the Turner stand really lift the players when they are attacking that goal line.
Even a small but vocal away following can be heard, I'm sure it motivates the players.
Regarding songs; the spice boys did i right, change all the swear words to something innocent - it has far more impact and can be funny to boot.
How about
The referee's a winker
Who's the naughty boy in the black
You're poop and you know you are
Classic spice boys was - "nice to know you're here....nice to know you're hear...now (pause for effect) go home"
